Lepidoptera ( le-pi-dop-t?-r?) is a large order of insects that includes moths and butterflies (called lepidopterans). It is one of the most widespread and widely recognizable insect orders in the world, encompassing moths and the three superfamilies of butterflies, skipper butterflies, and moth-butterflies. The term was coined by Linnaeus in 1735 and is derived from Ancient Greek ?ep?d?? (scale) and pte??? (wing). Comprising an estimated 174,250 species, in 126 families and 46 superfamilies, the Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest that the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and the Coleoptera.
Lepidopteran species are characterized by more than three derived features, some of the most apparent being the scales covering their bodies and wings, and a proboscis. The scales are modified, flattened "hairs", and give butterflies and moths their extraordinary variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Like most other insects, butterflies and moths are holometabolous, meaning they undergo complete metamorphosis. Mating and the laying of eggs are carried out by adults, normally near or on host plants for the larvae. The larvae are commonly called caterpillars, and are completely different from their adult moth or butterfly form, having a cylindrical body with a well-developed head, mandible mouth parts, and from 0 to 11 (usually 8) pairs of prolegs. As they grow, these larvae will change in appearance, going through a series of stages called instars. Once fully matured, the larva develops into a pupa, referred to as a chrysalis in the case of butterflies. A few butterflies and many moth species spin a silk case or cocoon prior to pupating, while others do not, instead going underground.
The Lepidoptera have, over millions of years, evolved a wide range of wing patterns and coloration ranging from drab moths akin to the related order Trichoptera, to the brightly colored and complex-patterned butterflies. Accordingly, this is the most recognized and popular of insect orders with many people involved in the observation, study, collection, rearing of and commerce in these insects. A person who collects or studies this order is referred to as a lepidopterist.
Butterflies and moths play an important role in the natural ecosystem as pollinators and as food in the food chain; conversely, their larva are considered very problematic to vegetation in agriculture, as their main source of food is often live plant matter. In many species, the female may produce anywhere from 200 to 600 eggs, while in others the number may go as high as 30,000 eggs in one day. The caterpillars hatching from these eggs can cause damage to large quantities of crops. Many moth and butterfly species are of economic interest by virtue of their role as pollinators, the silk they produce or as pest species.
The word Lepidoptera comes from the Latin word for "scaly wing", from the Ancient Greek ?ep?? (lepis) meaning scale and pte??? (pteron) meaning wing. Sometimes the term Rhopalocera is u sed to group the species that are butterflies, derived from the Ancient Greek ??pa??? (rhopalon):4150 and ???a? (k?ras):3993 meaning "club" and "horn", respectively; coming from the shape of the antennae of butterflies.
The origins of the common names "butterfly"and "moth" are varied and often obscure. The English word butterfly is from Old English buttorfleoge, with many variations in spelling. Other than that, the origin is unknown, although it could be derived from the pale yellow color of many species' wings suggesting the color of butter. The species of Heterocera are commonly called moths. The origins of the English word moth are more clear, deriving from the Old English mo??e" (cf. Northumbrian dialect moh?e) from Common Germanic (compare Old Norse motti, Dutch mot and German Motte all meaning "moth"). Perhaps its origins are related to Old English ma?a meaning "maggot" or from the root of "midge", which until the 16th century was used mostly to indicate the larva, usually in reference to devouring clothes.
The etymological origins of the word "caterpillar", the larval form of butterflies and moths, are from the early 16th century, from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose: cate, cat (from Latin cattus) + pelose, hairy (from Latin pilosus).
Distribution and diversity
Lepidoptera are among the most successful groups of insects. They are found on all continents, except Antarctica. Lepidoptera inhabit all terrestrial habitats ranging from desert to rainforest, from lowland grasslands to montane plateaus but almost always associated with higher plants, especially angiosperms (flowering plants). Among the most northern dwelling species of butterflies and moths is the Arctic Apollo (Parnassius arcticus), which is found in the Arctic Circle in northeastern Yakutia, at an altitude of 1500 meters above sea level. In the Himalayas, various Apollo species such as Parnassius epaphus, besides others, have been recorded to occur up to an altitude of 6,000 meters above sea level.:221
Some lepidopteran species exhibit symbiotic, phoretic, or parasitic life-styles, inhabiting the bodies of organisms rather than the environment. Coprophagous pyralid moth species, called sloth moths, such as Bradipodicola hahneli and Cryptoses choloepi, are unusual in that they are exclusively found inhabiting the fur of sloths, mammals found in Central and South America. Two species of Tinea moths have been recorded as feeding on horny tissue and have been bred from the horns of cattle. The larva of Zenodochium coccivorella is an internal parasite of the coccid Kermes species. Many species have been recorded as breeding in natural materials or refuse such as owl pellets, bat caves, honey-combs or diseased fruit.
Of the approximately 174,250 lepidopteran species described until 2007, butterflies and skippers are estimated to comprise approximately 17,950, with moths making up the rest. The vast majority of Lepidoptera are to be found in the tropics, but substantial diversity exists on most continents. North America has over 700 species of butterflies and over 11,000 species of moths, while there are about 400 species of butterflies and 14,000 species of moths reported from Australia. The diversity of Lepidoptera in each faunal region has been estimated by John Heppner in 1991 based partly on actual counts from the literature, partly on the card indices in the Natural History Museum (London) and the National Museum of Natural History (Washington), and partly on estimates::726
Lepidoptera are morphologically distinguished from other orders principally by the presence of scales on the external parts of the body and appendages, especially the wings. Butterflies and moths vary in size from microlepidoptera only a few millimeters long, to conspicuous animals with a wingspan of many inches, such as the Monarch butterfly and Atlas moth.:246 Lepidopterans undergo a four-stage life cycle: egg; larva or caterpillar; pupa or chrysalis; and imago (plural: imagines) / adult and show many variations of the basic body structure, which have evolved to gain advantages in lifestyle and distribution.
The head is where many sensing organs and the mouth parts are found. Like the adult, the larva also have a toughened, or sclerotized head capsule. Here, there are two compound eyes, and chaetosema, raised spots or clusters of sensory bristles unique to Lepidoptera, even though many taxa have lost one or both of these spots. The antennae have a wide variation in form among species and even between different sexes. The antennae of butterflies are usually filiform and shaped like clubs, those of the skippers are hooked while those of moths have flagellar segments variously enlarged or branched. Some moths have antennae that are enlarged, or tapered and hooked at the ends.:559-560
The maxillary galeae are modified and form an elongated proboscis. The proboscis consists of one to five segments, usually kept coiled up under the head by small muscles when it is not being used to suck up nectar from flowers or other liquids. Some basal moths still have mandibles, or separate moving jaws, like their ancestors and these form the family Micropterigidae.:560
The larvae, called caterpillars, have a toughened head capsule. Caterpillars lack the proboscis and have separate chewing mouthparts. These mouthparts, called mandibles, are used to chew up the plant matter that the larvae eat. The lower jaw, or labium, is weak but may carry a spinneret, an organ used to create silk. The head is made of large lateral lobes, each having an ellipse of up to six simple eyes.:562-563
The thorax is made of three fused segments, the prothorax, mesothorax, and metathorax, each with a pair of legs. The first segment contains the first pair of legs. In some males of the butterfly family Nymphalidae, the fore-legs are greatly reduced and are not used for walking or perching.:586 The three pairs of legs are covered with scales. Lepidoptera also have olfactory organs on their feet, which aid the butterfly in "tasting" or "smelling" out its food. In the larval form there are 3 pairs of true legs, with 0?11 pairs of abdominal legs (usually 8) and hooklets, called apical crochets.
The two pairs of wings are found on the middle and third segment, or mesothorax and metathorax respectively. In the more recent genera, the wings of the second segment are much more pronounced, although some more primitive forms have similarly sized wings of both segments. The wings are covered in scales arranged like shingles, which form an extraordinary variety of colors and patterns. The mesothorax is designed to have more powerful muscles to propel the moth or butterfly through the air, with the wing of this segment (forewing) having a stronger vein structure.:560 The largest superfamily, Noctuidae, have the wings modified to act as Tympanal or hearing organs
The caterpillar has an elongated soft body that may have hair-like or other projections, 3 pairs of true legs, with 0?11 pairs of abdominal legs (usually 8) and hooklets, called apical crochets. The thorax will usually have a pair of legs on each segment. The thorax is also lined with many spiracles on both the mesothorax and metathorax, except for a few aquatic species, who instead have a form of gill.:563
The abdomen, which is less sclerotized than the thorax, consists of 10 segments with membranes in between allowing for articulated movement. The sternum, on the first segment, is small in some families and is completely absent in others. The last 2 or 3 segments form the external parts of the species' sex organs. The genitalia of Lepidoptera are highly varied and are often the only means of differentiating between species. Male genitals include a valva, which is usually large, as it is used to grasp the female during mating. Female genitalia include three distinct sections.
In the females of basal moths, there is only one sex organ, which is used for copulation and as a ovipositor, or egg laying organ. 98% of moth species have a separate organ for mating, and an external duct that carries the sperm from the male.:561
The abdomen of the caterpillar has 4 pairs of prolegs, normally located on the third to sixth segments of the abdomen, and a separate pair of prolegs by the anus, which have a pair of tiny hooks called crotchets. These aid in gripping and walking, especially in species that lack many prolegs (e. g. larvae of Geometridae). In some basal moths, these prolegs may be on every segment of the body, while prolegs may be lost completely in other groups, which are more adapted to boring and living in sand (e. g., Prodoxidae and Nepticulidae respectively).:563
The wings, head parts of thorax and abdomen of Lepidoptera are covered with minute scales, from which feature the order 'Lepidoptera' derives its names, the word "lepteron" in Ancient Greek meaning 'scale'. Most scales are lamellar, or blade-like and attached with a pedicel, while other forms may be hair-like or specialized as secondary sexual characteristics. The lumen or surface of the lamella, has a complex structure. It gives color either due to the pigmentary colors contained within or due to its three-dimensional structure. Scales provide a number of functions, which include insulation, thermoregulation, aiding gliding flight, among others, the most important of which is the large diversity of vivid or indistinct patterns they provide, which help the organism protect itself by camouflage, mimicry, and to seek mates.
Electron microscopic images of scales
In the reproductive system of butterflies and moths, the male genitalia are complex and unclear. In females there are three types of genitalia based on the relating taxa: monotrysian, exoporian, and ditrysian. In the monotrysian type there is an opening on the fused segments of the sterna 9 and 10, which act as insemination and oviposition. In the exoporian type (in Hepaloidae and Mnesarchaeoidea) there are two separate places for insemination and oviposition, both occurring on the same sterna as the monotrysian type, i.e. 9 and 10. The ditrysian groups have an internal duct that carry sperm, with separate openings for copulation and egg-laying In most species the genitalia are flanked by two soft lobes, although they may be specialized and sclerotized in some species for ovipositing in area such as crevices and inside plant tissue. Hormones and the glands that produce them run the development of butterflies and moths as they go through their life cycle, called the endocrine system. The first insect hormone PTTH (Prothoracicotropic hormone) operates the species life cycle and diapause (see the relates section). This hormone is produced by corpora allata and corpora cardiaca, where it is also stored. Some glands are specialized to perform certain task such as producing silk or producing saliva in the palpi.:65, 75 While the corpora cardiaca produce PTTH, the corpora allata also produces jeuvanile hormones, and the prothorocic glands produce moulting hormones.
In the digestive system, the anterior region of the foregut has been modified to form a pharyngeal sucking pump as they need it for the food they eat, which are for the most part liquids. An esophagus follows and leads to the posterior of the pharynx and in some species forms a form of crop. The midgut is short and straight, with the hindgut being longer and coiled. Ancestors of lepidopteran species, stemming from Hymenoptera, had midgut ceca, although this is lost in current butterflies and moths. Instead, all the digestive enzymes other than initial digestion, are immobilized at the surface of the midgut cells. In larvae, long-necked and stalked goblet cells are found in the anterior and posterior midgut regions, respectively. In insects, the goblet cells excrete positive potassium ions, which are absorbed from leaves ingested by the larvae. Most butterflies and moths display the usual digestive cycle, however species that have a different diet require adaptations to meet these new demands.:279
In the circulatory system, hemolymph, or insect blood, is used to circulate heat in a form of thermoregulation, where muscles contraction produces heat, which is transferred to the rest of the body when conditions are unfavorable. In lepidopteran species, hemolymph is circulated through the veins in the wings by some form of pulsating organ, either by the heart or by the intake of air into the trachea.:69 Air is taken in through spiracles along the sides of the abdomen and thorax supplying the trachea with oxygen as it goes through the lepidopteran's respiratory system. There are three different tracheae supplying oxygen diffusing oxygen throughout the species body: The dorsal, ventral, and visceral. The dorsal tracheae supply oxygen to the dorsal musculature and vessels, while the ventral tracheae supply the ventral musculature and nerve cord, and the visceral tracheae supply the guts, fat bodies, and gonads.:71, 72
Polymorphism is the appearance of forms or "morphs", which differ in color and number of attributes within a single species.:163 In Lepidoptera, polymorphism can be seen not only between individuals in a population, but also between the sexes as sexual dimorphism, between geographically separated populations in geographical polymorphism and also between generations flying at different seasons of the year (seasonal polymorphism or polyphenism). In some species, the polymorphism is limited to one sex, typically the female. This often includes the phenomenon of mimicry when mimetic morphs fly alongside non-mimetic morphs in a population of a particular species. Polymorphism occurs both at specific level with heritable variation in the overall morphological design of individuals as well as in certain specific morphological or physiological traits within a species.
Environmental polymorphism, in which traits are not inherited, is often termed as polyphenism. Polyphenism in Lepidoptera is commonly seen in the form of seasonal morphs especially in the butterfly families of Nymphalidae and Pieridae. An Old World pierid butterfly, the Common Grass Yellow (Eurema hecabe) has a darker summer adult morph, triggered by a long day exceeding 13 hours in duration, while the shorter diurnal period of 12 hours or less induces a paler morph in the post-monsoon period. Polyphenism also occurs in caterpillars, an example being the Peppered Moth, Biston betularia.
Geographical polymorphism is where geographical isolation causes a divergence of a species into different morphs. A good example is the Indian White Admiral Limenitis procris, which has five forms, each geographically separated from the other by large mountain ranges.:26 An even more dramatic showcase of geographical polymorphism is the Apollo butterfly (Parnassius apollo). Due to the Apollos living in small local populations, having no contact with each other, but because of the strong stenotopic species and weak migration ability interbreeding between populations of one species practically does not occur; they form over 600 different morphs, with the size of spots on the wings of which varies greatly.

Sexual dimorphism is the occurrence of differences between males and females in a species. In Lepidoptera, sexual dimorphism is widespread and almost completely determined by genetic determination. Sexual dimorphism is present in all families of the Papilionoidoea and more prominent in the Lycaenidae, Pieridae and certain taxa of the Nymphalidae. Apart from color variation, which may differ from slight to completely different color-pattern combinations, secondary sexual characteristics may also be present.:25 Different genotypes maintained by natural selection may also be expressed at the same time. Polymorphic and/or mimetic females occur in the case of some taxa in the Papilionidae primarily to obtain a level of protection not available to the male of their species. The most distinct case of sexual dimorphism is that of adult females of many Psychidae species who have only vestigial wings, legs, and mouthparts as compared to the adult males who are strong fliers with well-developed wings and feathery antennae.
Reproduction and development
Species of Lepidoptera undergo holometabolism or "complete metamorphosis". Their life cycle normally consists of an egg, larva, pupa, and an imago or adult. The larvae are commonly called caterpillars, and the pupae of moths that are encapsulated in silk are called cocoons while the uncovered pupae of butterflies are called c hrysalides.
Males usually get a head start, and start eclosion or emergence, earlier than females and peak in numbers before females. Both of the sexes are sexually mature by the time of eclosion.:564 Butterflies and moths normally don't associate with each other, except for migrating species, staying relatively asocial. Mating begins with an adult (female or male) attracting a mate, normally using visual stimuli, especially in diurnal species like most butterflies. However, the females of most nocturnal species, including almost all moth species, use pheromones to attract males, sometimes from long distances. Some species engage in a form of acoustic courtship, or attract mates using sound or vibration such as the polka-dot wasp moth, Syntomeida epilais.
Adaptations include undergoing one seasonal generation, two or even more, called voltinism (Univoltism, bivoltism and multivism respectively). Most lepidoptera in temperate climates are univoltine, while in tropical climates most have two seasonal broods. Some others may take advantage of any opportunity they can get, and mate continuously throughout the year. These seasonal adaptations are controlled by hormones, and these delays in reproduction are called diapause.:567 Many lepidopteran species, after mating and laying their eggs, die shortly afterwards, having only lived for a few days after eclosion. Others may still be active for several weeks and then overwinter and become sexually active again when the weather becomes more favorable, or diapause. The sperm of the male that mated most recently with the female is most likely to have fertilized the eggs but the sperm from a prior mating may still prevail.:564
Lepidoptera usually reproduce sexually and are oviparous (egg-laying), though some species exhibit live birth in a process called ovoviviparity. There are a variety of differences in egg-laying and the number of eggs laid. Some species simply drop their eggs in flight (these species normally have polyphagous larvae, meaning they eat a variety of plants e. g., hepialids and some nymphalids) while most Lepidoptera will lay their eggs near or on the host plant that the larvae feed on. The number of eggs laid may vary from only a few to several thousand. The females of both butterflies and moths select the host plant instinctively primarily by chemical cues.:564
The egg is covered by a hard-ridged protective outer layer of shell, called the chorion. It is lined with a thin coating of wax, which prevents the egg from drying out before the larva has had time to fully develop. Each egg contains a number of micropyles, or tiny funnel-shaped openings at one end, the purpose of which is to allow sperm to enter and fertilize the egg. Butterfly and moth eggs vary greatly in size between species, but they are all either spherical or ovate.
The egg stage lasts a few weeks in most butterflies but eggs laid close to winter, especially in temperate regions, go through a diapause, and hatching may be delayed until spring. Other butterflies may lay their eggs in the spring and have them hatch in the summer. These butterflies are usually northern species (e. g. Nymphalis antiopa).
The larvae or caterpillars are the first stage in the life cycle after hatching. Caterpillars, are "characteristic polypod larvae with cylindrical bodies, short thoracic legs and abdominal prolegs (pseudopods)". They have a toughened (sclerotised) head capsule, mandibles (mouthparts) for chewing, and a soft tubular, segmented body, that may have hair-like or other projections, three pairs of true legs, and additional prolegs (up to five pairs). The body consists of thirteen segments, of which three are thoracic and ten are abdominal. Most larvae are herbivores, but a few are carnivores (some eat ants or other caterpillars) and detritivores.
Different herbivore species have adapted to feed on every part of the plant and are normally considered pests to their host plant; some species have been found to lay their eggs on the fruit and other species lay their eggs on clothing or fur (e. g., Tineola bisselliella, the common clothes moth). Some species are carnivorous and others are even parasitic. Some lycaenid species such as Maculinea rebeli are social parasites of Myrmica ants nests. A species of Geometridae from Hawaii has carnivorous larvae that catch and eat flies. Some pyralid caterpillars are aquatic.
The larvae develop rapidly with several generations in a year; however, some species may take up to 3 years to develop and exceptional examples like Gynaephora groenlandica take as long as seven years. The larval stage is where the feeding and growing stages occur, and the larvae periodically undergo hormone-induced ecdysis, developing further with each instar, until they undergo the final larval-pupal molt. Lepidoptera pupa, known as Pupa#Chrysalis, have functional mandibles and with appendages fused or glued to the body in most species, while the pupal mandibles are not functional in others.
The larvae of both butterflies and moths exhibit mimicry to deter potential predators. Some caterpillars have the ability to inflate parts of their head to appear snake-like. Many have false eye-spots to enhance this effect. Some caterpillars have special structures called osmeteria, which are averted to produce smelly chemicals. These are used in defense. Host plants often have toxic substances in them and caterpillars are able to sequester[disambiguation needed ] these substances and retain them into the adult stage. This helps making them unpalatable to birds and other predators. Such unpalatability is advertised using bright red, orange, black or white warning colors. The toxic chemicals in plants are often evolved specifically to prevent them from being eaten by insects. Insects in turn develop countermeasures or make use of these toxins for their own survival. This "arms race" has led to the coevolution of insects and their host plants.
Any form of wings are externally visible on the larva, however when larvae are dissected, developing wings can be seen as disks, which can be found on the second and third thoracic segments, in place of the spiracles that are apparent on abdominal segments. Wing disks develop in association with a trachea that runs along the base of the wing, and are surrounded by a thin peripodial membrane, which is linked to the outer epidermis of the larva by a tiny duct. Wing disks are very small until the last larval instar, when they increase dramatically in size, are invaded by branching tracheae from the wing base that precede the formation of the wing veins, and begin to develop patterns associated with several landmarks of the wing.
Near pupation, the wings are forced outside the epidermis under pressure from the hemolymph, and although they are initially quite flexible and fragile, by the time the pupa breaks free of the larval cuticle they have adhered tightly to the outer cuticle of the pupa (in obtect pupae). Within hours, the wings form a cuticle so hard and well-joined to the body that pupae can be picked up and handled without damage to the wings.
After about 5 to 7 instars,:26?28 or molts, certain hormones, like prothoracicotropic hormone, stimulate the production of ecdysone, which initiates insect molting. Then, the larva puparium, a sclerotized or hardened cuticle of the last larval instar, develops into the pupa. Depending on the species, the pupa may be covered in silk and attached to many different types of debris or may not be covered at all. The pupa stays attached to the leaf by silk spun by the caterpillar before it spins the silk for the full pupa.:566 Features of the imago are externally recognizable in the pupa. All the appendages that are found on the adult head and thorax are found cased inside the cuticle (antennae, mouthparts, etc.), with the wings wrapped around, adjacent to the antennae.:564
While encased, some of the lower segments are not fused, and are able to move using small muscles found in between the membrane. Moving may help the pupa, for example, escape the sun, which would otherwise kill it. The pupa of the Mexican jumping bean moth (Cydia deshaisiana) does this. The larvae cut a trapdoor in the bean (species of Sebastiania) and use the bean as a shelter. When there is a sudden rise in temperature, the pupa inside twitches and jerks, pulling on the threads inside. Wiggling may also help to deter parasitoid wasps from laying eggs on the pupa. Other species of moth are able to make clicks to deter predators.:564, 566
The length of time before the pupa ecloses (emerges) varies greatly. The monarch butterfly may stay in its chrysalis for two weeks, while other species may need to stay for more than 10 months in diapause. The adult will emerge from the pupa either by using abdominal hooks or from projections located on the head. The mandibles found in the most primitive moth families are used to escape from their cocoon (e. g., Micropterigoidea).:564
Most lepidopteran species do not live long after eclosion, only needing a few days to find a mate and then lay their eggs. Others may remain active for from one to several weeks or go through diapause, overwintering as monarch butterflies do, or waiting out environmental stress. Some adult species of Microlepidoptera go through a stage where there is no reproductive-related activity lasting through summer and winter, followed by mating and oviposition, or egg laying, in the early spring.:564
While most butterflies and moths are terrestrial, many species of Pyralidae are truly aquatic with all stages except the adult occurring in water. Many species from other families such as Arctiidae, Nepticulidae, Cosmopterygidae, Tortricidae, Olethreutidae, Noctuidae, Cossidae and Sphingidae are aquatic or semi-aquatic.:22
Flight is an important aspect of the lives of butterflies and moths and is used for evading predators, searching for food and finding mates in a timely manner as lepidopteran species do not live long after ecl osion. It is the main form of locomotion in most species. In lepidoptera, the forewings and hindwings are mechanically coupled and flap in synchrony. Flight is anteromotoric, or being driven primarily by action of the forewings. Although it has been reported that lepidopteran species can still fly when their hindwings are cut off, it reduces their linear flight and turning capabilities.
Lepidopteran species have to be warm, about 77 to 79 ?F (25 to 26 ?C) in order to fly. They depend on their body temperature being sufficiently high and since they can't regulate it themselves, this is dependent on their environment. Butterflies living in cooler climates may use their wings to warm their bodies. They will bask in the sun, spreading out their wings so that they get maximum exposure to the sunlight. In hotter climates butterflies can easily overheat, so they are usually active only during the cooler parts of the day, early morning, late afternoon or early evening. During the heat of the day they rest in the shade. Some larger thick-bodied moths (e. g. Sphingidae) can generate their own heat to a limited degree by vibrating their wings. The heat generated by the flight muscles warms the thorax while the temperature of the abdomen is unimportant for flight. To avoid overheating some moths rely on hairy scales, internal air sacs, and other structures to separate the thorax and abdomen and keep the abdomen cooler.
Some species of butterfly can reach fast speeds, such as the Southern Dart, which can go as fast as 48.4 km/h. Sphingids are some of the fastest flying insects, some are capable of flying at over 50 km/h (30 miles per hour), having a wingspan of 35?150 mm. In some species, there is sometimes a gliding component to their flight. Flight occurs either as hovering, or as forward or backward motion. In butterfly and in moth species, like hawk moths, hovering is important in that they need to hover over flowers when feeding on the nectar.
Navigation is important to lepidoptera species, especially for those that migrate. Butterflies, which have more species that migrate, have been shown to navigate using time compensated sun compasses. They can see polarized light and therefore can orient even in cloudy conditions. The polarized light in the region close to the ultraviolet spectrum is suggested to be particularly important. It is suggested that most migratory butterflies are those that live in semi-arid areas where breeding seasons are short. The life-histories of their host plants also influence the strategies of the butterflies. Other theories include the use of landscapes. Lepidoptera may use coastal lines, mountains and even roads to orient themselves. Above sea it has been observed that the flight direction is much more accurate if the coast is still visible.
Many studies have also shown that moths navigate. One study showed that many moths may use the Earth's magnetic field to navigate, as a study of the moth Heart and Dart suggests. Another study, this time of the migratory behavior of the Silver Y, showed that even at high altitudes the species can correct its course with changing winds, and prefers flying with favourable winds, suggesting a great sense of direction. Aphrissa statira in Panama loses its navigational capacity when exposed to a magnetic field, suggesting it uses the Earth?s magnetic field.
Moths exhibit a tendency to circle artificial lights repeatedly. This suggests that they use a technique of celestial navigation called transverse orientation. By maintaining a constant angular relationship to a bright celestial light, such as the Moon, they can fly in a straight line. Celestial objects are so far away, that even after traveling great distances, the change in angle between the moth and the light source is negligible; further, the moon will always be in the upper part of the visual field or on the horizon. When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon. The moth instinctively attempts to correct by turning toward the light, causing airborne moths to come plummeting downwards, and?at close range?which results in a spiral flight path that gets closer and closer to the light source. Other explanations have been suggested, such as the idea that moths may be impaired with a visual distortion called a Mach band by Henry Hsiao in 1972. He stated that they fly towards the darkest part of the sky in pursuit of safety and are thus inclined to circle ambient objects in the Mach band region.
Lepidopteran migration is usually seasonal, the insects moving to escape dry seasons or other disadvantageous conditions. Most lepidopterans that migrate are butterflies, the distance travelled varying from short to very long journeys. Some butterflies that migrate include the Mourning Cloak, Painted Lady, American Lady, Red Admiral, and the Common Buckeye.:29?30 Particularly famous migrations are those of the Monarch butterfly from Mexico to northern United States and southern Canada, a distance of about 4,000?4,800 km (2,500?3,000 mi). Other well known migratory species include the Painted Lady and several of the danaine butterflies. Spectacular and large scale migrations associated with the Monsoons are seen in peninsular India. Migrations have been studied in more recent times using wing tags and also using stable hydrogen isotopes.
Moths also undertake migrations, an example being the uraniids. Urania fulgens undergoes population explosions and massive migrations that may be not surpassed by any other insect in the Neotropics. In Costa Rica and Panama, the first population movements may begin in July and early August and, depending on the year, may be very massive, continuing unabated for as long as five months.
Pheromones are commonly involved in mating rituals among species, especially moths, but they are also an important aspect of other forms of communication. Usually the pheromones are produced by either the male or the female and detected by members of the opposite sex with their antennae. In many species, a gland between the eighth and ninth segment under the abdomen in the female produces the pheromones. Communication can also occur through stridulation, or producing sounds by rubbing various parts of the body together.
Moths are known to engage in acoustic forms of communication; most often species engage use it in a form of acoustic courtship, attracting mates using sound or vibration. Like most other insects, moths pick up these sounds using tympanic membranes in the abdomen. An example is that of the polka-dot wasp moth (Syntomeida epilais), which produce sounds with a frequency above that normally detectable by humans (~20kHZ). These sounds also function as tactile communication, or communication through touch, as they stridulate, or vibrate a substrate like leaves and stems.
Most moths lack bright colors as many species use coloration as camouflage but butterflies engage in visual communication. Female cabbage butterflies, for example, use ultraviolet light to communicate, with scales colored in this range on the dorsal wing surface. When they fly, each down stroke of the wing creates a brief flash of ultraviolet light that the males apparently recognize as the flight signature of a potential mate. These flashes from the wings may attract several males who engage in aerial courtship displays.
One of the most important adaptations is diapause, or delay in development in response to regularly and recurring periods of adverse environmental conditions (winter, dry season, etc.). Diapause normally occurs in eggs, or as a reproductive delay in adults. Butterflies like the monarch may undergo diapause during winter, where they undergo a form of hibernation, lying dormant on trees for protection after their large scale migration. Seasonal adaptations such as voltism, where they may reproduce one or more times annually are due to diapause. This response to environmental stress is controlled by hormones and is necessary to survival during unfavorable times, especially in northern areas and high mountains where winter is regular and harsh. For example, in the Mediterranean area, larvae feed during the spring when the vegetation flourishes, then undergo diapause in the summer during drought, and hibernate in the winter.:567c
Moths and Butterflies are important in the natural ecosystem. They are integral participants in the food chain, having co-evolved with flowering plants and predators, lepidopteran species have formed a network of trophic relationships between autotrophs and heterotrophs, which are included in the stages of Lepidoptera larvae, pupae and adults. Larvae and pupae are links in the diet of birds and parasitic entomophagous insects. The adults are included in food webs in a much broader range of consumers (including birds, small mammals, reptiles, etc.).:567
Def ense and predation
Lepidopteran species are soft bodied, fragile and almost defenseless while the immature stages move slowly or are immobile, hence all stages are exposed to predation. Adult butterflies and moths are predated upon by birds, lizards, amphibians, dragonflies and spiders, besides others. Caterpillars and pupa fall prey, not only to birds but invertebrate predators, small mammals, as well as fungi and bacteria. Parasitoid and parasitic wasps and flies may lay eggs in the caterpillar, which eventually kill it as they hatch inside its body and eat its tissues. Insect-eating birds are probably the worst predators. Lepidoptera, especially the immature stages, are an ecologically important food to many insectivorous birds, such as the Great Tit in Europe.
An "evolutionary arms race" can be seen between predator and prey species. Lepidoptera have developed a number of strategies for defense and protection including evolution of morphological characters and changes in ecological life-style and in behavior. These include aposematism, mimicry, camouflage, development of threat patterns and displays and so on. Only a few birds, such as the nightjars, hunt nocturnal Lepidoptera and their main enemy are bats. Again, an "evolutionary race" exists, which has led to numerous evolutionary adaptations of moths to escape from their main predators, such as the ability to hear ultrasonic sounds, or even to emit sounds in some cases. Lepidoptera eggs are also predated upon. Some caterpillars, such as the zebra swallowtail butterfly larvae, are cannibalistic and may eat other larvae of the same species. Lepidopteran species rely on a variety of strategies.
Some species of lepidoptera are poisonous to predators, such as the Monarch butterfly in the Americas, Atrophaneura species (roses, windmills etc.) in Asia, as well as Papilio antimachus and the birdwings, the largest butterflies in Africa and Asia respectively. They obtain their toxicity by sequestering the chemicals from the plants they eat into their own tissues. Some Lepidoptera manufacture their own toxins. Predators that eat poisonous butterflies and moths may become sick and vomit violently, learning not to eat those types of species. A predator who has previously eaten a poisonous lepidopteran may avoid other species with similar markings in the future, thus saving many other species as well. Toxic butterflies and larvae tend to develop bright colors, striking patterns as an indicator to predators about their toxicity. This phenomenon is known as aposematism. Other caterpillars emit bad smells to ward off predators. Some caterpillars, especially members of Papilionidae, contain an osmeterium, a Y-shaped protrusible gland found in the prothoracic segment of the larvae. When threatened, the caterpillar emits unpleasant smells from the organ to ward off the predators.
Camouflage is also important defense strategies, which involves the use of coloration or shape to blend into the surrounding environment. Some lepidopteran species blend with its surroundings, making them difficult to be spotted by predators. Caterpillars can be shades of green that matches its host plant. Others look like inedible objects, such as twigs or leaves. The larvae of some species, such as the Common Mormon (Papilio polytes) and the Western Tiger Swallowtail look like bird droppings. For example, adult Sesiidae species (also known as clearwing moths) have a general appearance that is sufficiently similar to a wasp or hornet to make it likely that the moths gain a reduction in predation by Batesian mimicry. Eyespots are a type of automimicry used by some butterflies and moths. In butterflies, the spots are composed of concentric rings of scales of different colors. The proposed role of the eyespots is to deflect attention to predators. Their resemblance to eyes provokes the predator's instinct to attack these wing patterns.
Batesian and M?llerian mimicry complexes are commonly found in Lepidoptera. Genetic polymorphism and natural selection give rise to otherwise edible species (the mimic) gaining a survival advantage by resembling inedible species (the model). Such a mimicry complex is referred to as Batesian and is most commonly known by the mimicry by the limenitidine Viceroy butterfly of the inedible danaine Monarch. Later research has discovered that the Viceroy is, in fact more toxic than the Monarch and this resemblance should be considered as a case of M?llerian mimicry. In M?llerian mimicry, inedible species, usually within a taxonomic order, find it advantageous to resemble each other so as to reduce the sampling rate by predators who need to learn about the insects' inedibility. Taxa from the toxic genus Heliconius form one of the most well known M?llerian complexes. The adults of the various species now resemble each other so well that the species cannot be distinguished without close morphological observation and, in some cases, dissection or genetic analysis.
There is evidence moths are able to hear the range emitted by bats, which in effect causes flying moths to make evasive maneuvers because bats are a main predator of moths. Ultrasonic frequencies trigger a reflex action in the noctuid moth that cause it to drop a few inches in its flight to evade attack. Tiger moths in a defense emit clicks within the same range of the bats, which interfere with the bats, and foil their attempts to echolocate it.
Most species of Lepidoptera engage in some form of entomophily (more specifically psychophily and phalaenophily for butterflies and moths respectively), or the pollination of flowers. Most adult butterflies and moths feed on the nectar inside flowers, using their proboscis to reach the nectar hidden at the base of the petals. In the process, the adult brushes against the flower's stamen, on which the flower's reproductive pollen is made and stored. The pollen is transferred on appendages on the adult, who flies to the next flower to feed and unwittingly deposits the pollen on the stigma of the next flower, where the pollen germinates and fertilizes the seeds.:813-814
Flowers pollinated by butterflies tend to be large and flamboyant, being pink or lavender in color, frequently having a landing area, and are usually scented, as butterflies are typically day-flying. Since butterflies do not digest pollen (except for Heliconid species), more nectar is offered than pollen. The flowers have simple nectar guides with the nectaries usually hidden in narrow tubes or spurs, reached by the long tongue of the butterflies. Butterflies like the Thymelicus flavus have been observed to engage in flower constancy, which means that they are more likely to transfer pollen to other conspecific plants. This can be beneficial for the plants being pollinated, as flower constancy prevents the loss of pollen during different flights and the pollinators from clogging stigmas with pollen of other flower species.
Among the more important moth pollinators are the hawk moths (Sphingidae). Their behavior is similar to hummingbirds: Using rapid wing beats to keep hovered in front of flowers. Most being nocturnal or crepuscular, so moth-pollinated flowers (e.g., Silene latifolia ) tend to be white, night-opening, large and showy with tubular corollas and a strong, sweet scent produced in the evening, night or early morning. A lot of nectar is produced to fuel the high metabolic rates needed to power their flight. Other moths (e.g., noctuids, geometrids, pyralids) fly slowly and settle on the flower. They do not require as much nectar as the fast-flying hawk moths, and the flowers tend to be small (though they may be aggregated in heads).
Mutualism is a form of biological interaction where each individual involves benefits in some shape or form. An example of a mutualistic relationship would be the relationship shared by yucca moths (Tegeculidae) and their host, yucca flowers (Liliaceae). Female yucca moths enter the host flowers, collect the pollen into a ball using specialized maxillary palps, then move to the apex of the pistil where pollen is deposited on the stigma, and lay eggs into the base of the pistil where seeds will develop. The larvae develop in the fruit pod and feed on a portion of the seeds. Thus, both insect and plant benefit, forming a highly mutualistic relationship.:814 Another form of mutualism occurs between some larvae of butterflies and certain species of ants (e. g. Lycaenidae). The larvae communicate with the ants using vibrations that are transmitted through a substrate, such as the wood of a tree or stems, as well as using chemical signals. The ants provide some degree of protection to these larvae and they in turn gather honeydew secretions.
There are only 41 known species of parasitoid lepidoptera (1-Pyralidae; 40-Epipyropidae).:748 The larvae of the Greater and Lesser wax moths feed on the honeycomb inside bee nests and may become pests; they are also found in bumblebee and wasp nests, albeit to a lesser extent. In northern Europe the wax moth is regarded as the most serious parasitoid of the bumblebee, and is found only in bumblebee nests. In some areas in southern England as many as eighty percent of nests can be destroyed. Other parasitic larvae are known to prey upon cicadas and leaf hoppers.
In reverse, moths and butterflies may be subject to parasitic wasps and flies, which may lay eggs on the caterpillars, which hatch and feed inside its body resulting in death. Although, in a form of parasitism called idiobiont, the adult paralyzes the host, so as not to kill it but for it to live as long as possible, in order for the parasitic larvae to benefit the most. Another form of parasitism, is koinobiont, where the species live off their host while inside or endoparasitic. These parasites live inside the host caterpillar throughout its life cycle, or may affect it later on as an adult. In other orders, koinobionts include flies, a majority of coleopteran, and many hymenopteran parasitoids.:748-749 Some species may be subject to a variety of parasites, such as the Gypsy moth (Lymantaria dispar), which is attacked by a series of 13 species, in 6 different taxa throughout its life cycle.:750
In response to a parsitoid egg or larvae in the caterpillar's body, the plasmatocytes, or simply the host's cells can form a multilayered capsule that eventually cause the endoparasite to asphyxiate, and die. The process is called encapsulation, and is one of the caterpillar's only means of defense against parasitoids.:748
Other biological interactions
A few species of Lepidoptera are secondary consumers, or predators. These species typically prey upon the eggs of other insects, aphids, scale insects, or ant larvae.:567 Some caterpillars are cannibals, and others prey on caterpillars of other species (e. g. Hawaiian Eupithecia ). Those of the 15 species in Eupithecia that mirror inchworms, are the only known species of butterflies and moths that are ambush predators. There are 4 known species that eat snails. For example, the Hawai'ian caterpillar, (H. molluscivora), uses silk traps, in a manner similar to that of spiders to capture certain species of snails (typically Tornatellides).
Larvae of some species of moths of Tineidae, Gelechioidae and Noctuidae, besides others, feed on detritus, or organic material that is not living, such as fallen leaves and fruit, fungi, and animal products and turn it into humus.:567 Well known species include the cloth moths (Tineola bisselliella, T. pellionella, and T. tapetzella), which feed on detritus containing keratin, including hair, feathers, cobwebs, bird nests (particularly of Domestic Pigeons, Columba livia domestica) and fruits or vegetables. These species are important to ecosystems as they remove substances that would otherwise take a long time to decompose.
Evolution and systematics
 History of study
Linnaeus in Systema Naturae (1758) recognized three divisions of the Lepidoptera: Papilio, Sphinx and Phalaena, with seven subgroups in Phalaena. These persist today as 9 of the superfamilies of Lepidoptera. Other works on classification followed including those by Michael Denis & Ignaz Schifferm?ller (1775), Johan Christian Fabricius (1775) and Pierre Andr? Latreille (1796). Jacob H?bner described many genera, and the Lepidopteran genera were catalogued by Ferdinand Ochsenheimer and Georg Friedrich Treitschke in a series of volumes on the Lepidopteran fauna of Europe published between 1807 and 1835. Gottlieb August Wilhelm Herrich-Sch?ffer (several volumes, 1843?1856), and Edward Meyrick (1895) based their classifications primarily on wing venation. Sir George Francis Hampson worked on the 'Microlepidoptera' during this period and Philipp Christoph Zeller published The Natural History of the Tineinae also on Microlepidoptera (1855).
Among the first entomologists to study fossil insects and their evolution was Samuel Hubbard Scudder (1837?1911), who worked on butterflies. He published a study of the Florissant deposits of Colorado, including the exceptionally preserved Prodryas persephone. Andreas V. Martynov (1879?1938) recognized the close relationship between Lepidoptera and Trichoptera in his studies on phylogeny.
Major contributions in the 20th century included the creation of the monotrysia and ditrysia (based on female genital structure) by Borner in 1925 and 1939. Willi Hennig (1913?1976) developed the cladistic methodology and applied it to insect phylogeny. Niels P. Kristensen, E. S. Nielsen and D. R. Davis studied the relationships among monotrysian families and Kristensen worked more generally on insect phylogeny and higher Lepidoptera too. While it is often found that DNA-based phylogenies differ from those based on morphology, this has not been the case for the Lepidoptera; DNA phylogenies correspond to a large extent to morphology-based phylogenies.
Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidotera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.
 Fossil record
The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization, such as lakes and ponds, and their juvenile stage has only the head capsule as a hard part that might be preserved. The location and abundance of the most common moth species are indicative that mass migrations of moths occurred over the Palaeogene North Sea, which is why there is a serious lack of moth fossils. Yet there are fossils, some preserved in amber and some in very fine sediments. Leaf mines are also seen in fossil leaves, although the interpretation of them is tricky.
Putative fossil stem group representatives of Amphiesmenoptera (the clade comprising Trichoptera and Lepidoptera) are known from the Triassic.:567 The earliest known fossil lepidopteran is Archaeolepis mane from the Jurassic, about 190 million years ago in Dorset, UK. The fossil belongs to a small primitive moth-like species, and its wings are showing scales with parallel grooves under a scanning electron microscope and a characteristic wing venation pattern shared with Trichoptera (Caddisflies). Only two more sets of Jurassic lepidopteran fossils have been found, as well as 13 sets from the Cretaceous, which all belong to primitive moth-like families. Many more fossils are found from the Tertiary, and particularly the Eocene Baltic amber. The oldest genuine butterflies of the superfamily Papilionoidea have been found in the Paleocene MoClay or Fur Formation of Denmark. The best preserved fossil lepidopteran is the Eocene Prodryas persephone from the Florissant Fossil Beds.
Lepidoptera and Trichoptera (caddisflies) are more closely related than any other taxa, sharing many similarities that are lacking in other insect orders; for example the females of both orders are heterogametic, meaning they have two different sex chromosomes, whereas in most species the males are heterogametic and the females have two identical sex chromosomes. The adults in both orders display a particular wing venation pattern on their forewings. The larvae of both orders have mouth structures and gland with which they make and manipulate silk. Willi Hennig grouped the two sister orders into the Amphiesmenoptera superorder. This group probably evolved in the Jurassic, having split from the now extinct order Necrotaulidae.
Micropterigidae, Agathiphagidae and Heterobathmiidae are the oldest and most basal lineages of Lepidoptera. The adults of these families do not have the curled tongue or proboscis, that are found in most members order, but instead have chewing mandibles adapted for a special diet. Micropterigidae larvae feed on leaves, fungi, or liverworts (much like the Trichoptera). Adult Micropterigidae chew the pollen or spores of ferns. In the Agathiphagidae, larvae live inside kauri pines and feed on seeds. In Heterobathmiidae the larvae feed on the leaves of Nothofagus, the southern beech tree. These families also have mandibles in the pupal stage, which help the pupa emerge from the seed or cocoon after metamorphosis.
The Eriocraniidae have a short coiled proboscis in the adult stage, and though they retain their pupal mandibles with which they escaped the cocoon, their mandibles are non-functional thereafter. Most of these non-ditrysian families, are primarily leaf miners in the larval stage. In addition to the proboscis, there is a change in the scales among these basal lineages, with later lineages showing more complex perforated scales.
With the evolution of the Ditrysia in the mid-Cretaceous, there was a major reproductive change. The Ditrysia, which comprise 98% of the Lepidoptera, have two separate openings for reproduction in the females (as well as a third opening for excretion), one for mating, and one for laying eggs. The two are linked internally by a seminal duct. (In more basal lineages there is one cloaca, or later, two openings and an external sperm canal.) Of the early lineages of Ditrysia, Gracillarioidea and Gelechioidea are mostly leaf miners, but more recent lineages feed externally. In the Tineoidea, most species feed on plant and animal detritus and fungi, and build shelters in the larval stage.
The Yponomeutoidea is the first group to have significant numbers of species whose larvae feed on herbaceous plants, as opposed to woody plants. They evolved about the time that flowering plants underwent an expansive adaptive radiation in the mid-Cretaceous, and the Gelechioidea that evolved at this time also have great diversity. Whether the processes involved coevolution or sequential evolution, the diversity of the Lepidoptera and the angiosperms increased together.
In the so-called "Macrolepidoptera", which constitutes about 60% of lepidopteran species, there was a general increase in size, better flying ability (via changes in wing shape and linkage of the forewings and hindwings), reduction in the adult mandibles, and a change in the arrangement of the crochets (hooks) on the larval prolegs, perhaps to improve the grip on the host plant. Many also have tympanal organs, that allow them to hear. These organs evolved eight times, at least, because they occur on different body parts and have structural differences. The main lineages in the Macrolepidoptera are the Noctuoidea, Bombycoidea, Lasiocampidae, Mimallonoidea, Geometroidea and Rhopalocera. Bombycoidea plus Lasiocampidae plus Mimallonoidea may be a monophyletic group. The Rhopalocera, comprising the Papilionoidea (butterflies), Hesperioidea (skippers), and the Hedyloidea (moth-butterflies), are the most recently evolved. There is quite a good fossil record for this group, with the oldest skipper dating from 56 million years ago.
Taxonomy is the classification of species in selected taxa, the process of naming being called nomenclature. There are over 120 families in lepidoptera, in 45 to 48 superfamilies. Lepidoptera have always been, historically, classified in five suborders, one of which is of primitive moths that never lost the morphological features of its ancestors. The rest of the moths and butterflies make up ninety-eight percent of the other taxa, making Ditrysia. More recently, new findings of new taxa and larvae and pupa have aided in detailing the relationships of primitive taxa, phylogenetic analysis showing the primitive lineages to be paraphyletic compared to the rest of Lepidoptera lineages. Recently lepidopterists have abandoned clades like suborders, and those between orders and superfamilies.:569
- Zeugloptera is a clade with Micropterigoidea being its only family. Species of Micropterigoidea are practically living fossils, being one of the most primitive lepidopteran species, still retaining mandible mouthparts, unlike other clades of butterflies and moths. About 120 species are known worldwide, with more than half the species in the genus Micropteryx in the Paleartic region. There are only 2 known in North America (Epimartyria), with many more being found Asia and the southwest Pacific, particularly New Zealand with about 50 species.:569
- Glossata contains a majority of the species, with the most obvious difference is non-functioning mandibles, and elongated maxillary galeae or the proboscis. The basal clades still retaining some of the ancestral features of the wings such as similarly shaped fore- and hindwings with relatively complete venation. Glossata also contains the division Ditrysia, which contains 98% of all described species in Lepidoptera.:569
- Aglossata it is the second most primitive lineage of lepidoptera; being first described in 1952 by Lionel Jack Dumbleton. Agathiphagidae and Heterobathmiidae are the only families in Aglossata. Agathiphagidae only contains about 2 species in its genus Agathiphaga.:569. Agathiphaga queenslandensis and Agathiphaga vitiensis, being found along the north-eastern coast of Queensland, Australia, and in Fiji to Vanuatu and the Solomon Islands, respectively.
- Heterobathmiina was first described by Kristensen and Nielsen in 1979. There are about 10 species, which are day-flying, metallic moths, confined to southern South America, the adults eat the pollen of Nothofagus or Southern Beech and the larvae mine the leaves.:569
 Relationship to people
Artistic depictions of butterflies have been used in many cultures including as early as 3500 years ago, in Egyptian hieroglyphs. Today, butterflies are widely used in various objects of art and jewelry: mounted in frames, embedded in resin, displayed in bottles, laminated in paper, and in some mixed media artworks and furnishings. Butterflies have also inspired the "butterfly fairy" as an art and fictional character, including in the Barbie Mariposa film.
In many cultures the soul of a dead person is associated with the butterfly. As in Ancient Greece, where the word for butterfly ???? (psyche) also means soul and breath. In Latin, as in Ancient Greece, the word for "butterfly" papilio was associated with the soul of the dead. The skull-like marking on the thorax of the Death's-head Hawkmoth has helped these moths, particularly A. atropos, earn a negative reputation, such as associations with the supernatural and evil. The moth has been prominently featured in art and movies such as Un Chien Andalou (by Bu?uel and Dal?) and The Silence of the Lambs, and in the artwork of the Japanese metal band Sigh's album Hail Horror Hail. According to Kwaidan: Stories and Studies of Strange Things, by Lafcadio Hearn, a butterfly was seen in Japan as the personification of a person's soul; whether they be living, dying, or already dead. One Japanese superstition says that if a butterfly enters your guestroom and perches behind the bamboo screen, the person whom you most love is coming to see you. However, large numbers of butterflies are viewed as bad omens. When Taira no Masakado was secretly preparing for his famous revolt, there appeared in Kyoto so vast a swarm of butterflies that the people were frightened?thinking the apparition to be a portent of coming evil.
In the ancient Mesoamerican city of Teotihuacan, the brilliantly colored image of the butterfly was carved into many temples, buildings, jewelry, and emblazoned on incense burners in particular. The butterfly was sometimes depicted with the maw of a jaguar and some species were considered to be the reincarnations of the souls of dead warriors. The close association of butterflies to fire and warfare persisted through to the Aztec civilization and evidence of similar jaguar-butterfly images has been found among the Zapotec, and Maya civilizations.
The larvae of many Lepidopteran species are major pests in agriculture. Some of the major pests include Tortricidae, Noctuidae, and Pyralidae. The larvae of the Noctuidae genus Spodoptera (armyworms) and Helicoverpa (corn earworm) can cause extensive damage to certain crops. Helicoverpa zea larvae (cotton bollworms or tomato fruitworms) are polyphagous, meaning they eat a variety of crops, including tomatoes and cotton.
Butterflies and moths are one of the largest taxa to solely feed and be dependent on living plants, in terms of the number of species, and they are in many ecosystems make up the largest biomass to do so. In many species, the female may produce anywhere from 200 to 600 eggs, while in some others it may go as high as 30,000 eggs in one day. This creates many problems for agriculture, where many caterpillars can mow down acres of vegetation. Some reports estimate that there have been over 80,000 caterpillars of several different taxa feeding on a single oak tree. In some cases, phytophagous larvae can lead to the destruction of entire trees in relatively short periods of time.:567
Ecological ways of removing pest lepidoptera species are becoming more economically viable, as research has shown ways like introducing parasitic wasp and flies. For example Sarcophaga aldrichi, which the larvae feed upon the larvae of the Forest Tent Caterpillar Moth. Pesticides can affect other species other than the species they are targeted to eliminate, damaging the natural ecosystem. Another good biological pest control method is the use of pheromone traps. A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a Delta trap, water-pan trap, or funnel trap.
Species of moths that are detrivores would naturally eat detritus containing keratin, such as hairs or feathers. Well known species are cloth moths (T. bisselliella, T. pellionella, and T. tapetzella), feeding on foodstuffs that people find economically important, such cotton, linen, silk and wool fabrics as well as furs; furthermore they have been found on shed feathers and hair, bran, semolina and flour (possibly preferring wheat flour), biscuits, casein, and insect specimens in museums.
 Beneficial insects
Even though most butterflies and moths affect the economy negatively, some species are a valuable economic resource. The most prominent example is that of the Domesticated silkworm moth (Bombyx mori), the larvae of which make their cocoons out of silk, which can be spun into cloth. Silk is and has been an important economic resource throughout history. The species Bombyx mori has been domesticated to the point where it is completely dependent on mankind for survival. A number of wild moths such as Bombyx mandarina, and Antheraea species, besides others, provide commercially important silks.
The preference of the larvae of most Lepidopteran species to feed on a single species or limited range of plants is used as a mechanism for biological control of weeds in place of herbicides. The pyralid cactus moth was introduced from Argentina to Australia, where it successfully suppressed millions of acres of Prickly pear cactus.:567 Another species of the Pyralidae, called the alligator weed stem borer (Arcola malloi), was used to control the aquatic plant known as alligator weed (Alternanthera philoxeroides) in conjunction with the alligator weed flea beetle; in this case, the two insects work in synergy and the weed rarely recovers.
Breeding butterflies and moths, or butterfly gardening, has become an ecologically viable process of introducing species into the ecosystem for the better of benefiting it. Butterfly ranching in Papua New Guinea permits nationals of that country to 'farm' economically valuable insect species for the collectors market in an ecologically sustainable manner.
Lepidoptera feature prominently in entomophagy as food items on almost every continent. While in most cases, adults, larvae or pupae are eaten as staples by indigenous people, beondegi or silkworm pupae are eaten as a snack in -Korean cuisine while Maguey worm is considered a delicacy in Mexico. In the Carnia region of Italy, children catch and eat Zygaena moths in early summer. The ingluvies, despite having a very low cyanogenic content, serves as a convenient, supplementary source of sugar to the children who can include this resource as a seasonal delicacy at minimum risk.
Some larvae of both moths and butterflies have a form of hair that has been known to be a cause of human health problems. Caterpillar hairs sometimes have venomous toxins in them and species from approximately 12 families of moths or butterflies worldwide can inflict serious human injuries (Urticarial dermatitis and atopic asthma to osteochondritis, consumption coagulopathy, renal failure, and intracerebral hemorrhage). Skin rashes are the most common, but there have been fatalities. Lonomia is a frequent cause of economization in humans in Brazil, with 354 cases reported between 1989 and 2005. Lethality ranging up to 20% with death caused most often by intracranial hemorrhage.
These hairs have also been known to cause kerato-conjunctivitis. The sharp barbs on the end of caterpillar hairs can get lodged in soft tissues and mucus membranes such as the eyes. Once they enter such tissues, they can be difficult to extract, often exacerbating the problem as they migrate across the membrane. This becomes a particular problem in an indoor setting. The hairs easily enter buildings through ventilation systems and accumulate in indoor environments because of their small size, which makes it difficult for them to be vented out. This accumulation increases the risk of human contact in indoor environments.

- Species: ZipcodeZoo has pages for 272,943 species and subspecies in the Order Lepidoptera.
The Acrolepiidae family of moths are also known as False Diamondback moths. [more]
The Adelidae or fairy longhorn moths are a family of monotrysian moths in the lepidopteran infraorder Heteroneura. Most species have at least partially metallic patterns coloration and are diurnal, sometimes swarming around the tips of branches with an undulating flight. Others are crepuscular and have a drab coloration. Fairy longhorn moths have a wingspan of 4-28 millimeters, and males often have especially long antennae, 1-3 times as long as the forewing. [more]
Agathiphaga is a genus of moths in the family Agathiphagidae, known as kauri moths. This caddis fly-like lineage of primitive moths was first reported by Lionel Jack Dumbleton in 1952, as a new genus of Micropterigidae. [more]
The Agonoxenidae are a family of moths only contains four named species in the whole world ? all in the type genus ? if (e.g. following Nielsen et al., 1996) the Blastodacnidae are considered to be a separate family. Such a monotypic arrangement is fairly unusual in modern taxonomy without explicit need due to phylogenetic constraints, and with little reliable data on the latter, the traditional approach is followed here pending new studies. [more]
The Alucitidae or many-plumed moths are a family of moths with unusually modified wings. Both fore- and hind-wings consist of about six rigid spines, from which radiate flexible bristles creating a structure similar to a bird's feather. [more]
Anthelidae is a family of Australian lappet moths in the Lepidoptera order. It was previously included in the Lasiocampoidea superfamily, but a recent study resulted in reincluding the family in the superfamily Bombycoidea. [more]
Arctiidae is a large and diverse family of moths with around 11,000 species found all over the world, including 6,000 neotropical species. This family includes the groups commonly known as tiger moths (or tigers), which usually have bright colors, footmen (which are usually much drabber), lichen moths and wasp moths. Many species have 'hairy' caterpillars which are popularly known as woolly bears or woolly worms. The scientific name refers to this (Gk. a??t?? = a bear). Caterpillars may also go by the name 'tussock moths' (more usually this refers to Lymantriidae, however). [more]
Argyresthiinae is a subfamily of moths of the Yponomeutidae family, although it is treated as a valid family Argyresthiidae by some authors. [more]
Batrachedridae is a small family of moths. These are small, slender moths which rest with the wings wrapped tightly around the body. The taxonomy of this and related groups is often disputed. It was long thought to contain two genera, Batrachedra (many species) and Houdinia (a single species, Houdinia flexissima from New Zealand and surrounding islands). [more]
Bedelliidae is a small family of small, narrow-winged moths; most authorities recognize just a single genus, Bedellia, previously included in the family Lyonetiidae. The family is still included in the Lyonetiidae as the subfamily Bedelliinae by some authors. [more]
Blastobasidae is a family of moths in the superfamily Gelechioidea. Its species can be found almost anywhere in the world, though in some places they are not native but introduced by humans. In some arrangements, these moths are included in the case-bearer family (Coleophoridae) as subfamily Blastobasinae. The Symmocidae are sometimes included in the Blastobasidae (particularly if both are included in Coleophoridae) as subfamily or tribe. [more]
Bombycidae is a family of moths. The best-known species is Bombyx mori (Linnaeus) or silkworm, native to northern China and domesticated for millennia. Another well known species is Bombyx mandarina, also native to Asia. [more]
Brahmaeidae is a family of insects in the Lepidoptera order, commonly known as brahmin moths. [more]
Bucculatricidae or (Bucculatrigidae) is a family of moths. This small family has representatives in all parts of the world. Some authors place the group as a subfamily of the family Lyonetiidae. [more]
Carposinidae, the "fruitworm moths" is a family of insects in the lepidopteran order. These moths are narrower winged than Copromorphidae, with less rounded forewing tips. Males often have conspicuous patches of scales on either surface (Dugdale et al., 1999). The mouthparts are quite diagnostic, usually with prominent, upcurved "labial palps", the third segment long (especially in females), and the second segment covered in large scales. Unlike Copromorphidae, the "M2" and sometimes "M1" vein on the hindwings is absent. The relationship of Carposinidae relative to Copromorphidae needs further investigation. It is considered possible that the family is artificial, being nested within Copromorphidae (Dugdale et al., 1999). The Palearctic species have been revised by Diakonoff (1989). [more]
Castniidae, or castniid moths, is a small family of moths with fewer than 200 species: The majority are Neotropical with some in Australia and a few in south-east Asia. These are medium-sized to very large moths, usually with drab, cryptically-marked forewings and brightly colored hindwings. They have clubbed antennae and are day-flying, and are often mistaken for butterflies. Indeed some previous classification systems placed this family within the butterflies or skippers. The Neotropical species are commonly known as giant butterfly-moths, the Australian and Asian species as sun moths. The larvae are internal feeders, often on roots of epiphytes or on monocotyledons (Edwards et al., 1999: 184-188). [more]
Choreutidae, or "metalmark moths," are a family of insects in the lepidopteran order whose relationships have been long disputed. It was placed previously in the superfamily Yponomeutoidea in family Glyphipterigidae and in superfamily Sesioidea. It is now considered to represent its own superfamily (Minet, 1986). The relationship of the family to the other lineages in the group "Apoditrysia"  need a new assessment, especially with new molecular data. [more]
Coleophoridae is a family of small moths, belonging to the huge superfamily Gelechioidea. Collectively known as case-bearers, casebearing moths or case moths, this family is represented on all continents but the majority are found in temperate areas of the Northern Hemisphere. They are most common in the Palearctic, and rare in sub-Saharan Africa, South America and Australia; consequently, they probably originated (like most or all other Gelechioidea families) in northern Eurasia. [more]
Copromorphidae, the "tropical fruitworm moths" is a family of insects in the lepidopteran order. These moths have broad, rounded forewings, and well-camouflaged scale patterns. Unlike Carposinidae the mouthparts include "labial palps" with the second rather than third segment the longest. The position of the enigmatic New Zealand genus Isonomeutis in this family in uncertain, as it lacks the flimsy cuticle of the pupa characteristic of other Copromorphoidea. With other unusual structural characteristics of the caterpillar and adult, it could represent the sister lineage of all other extant members of this superfamily (Dugdale et al., 1999). The genus Sisyroxena from Madagascar is also notable for its unusual venation and wing scale sockets (Dugdale et al., 1999). [more]
Cosmopterigidae (cosmet moths) is a family of insects in the Lepidoptera order. These are small moths with narrow wings whose tiny larvae feed internally on the leaves, seeds, stems, etc of their host plants. There are about 1,500 described species. The family is most diverse in the Australian and Pacific region with about 780 species. [more]
Cosmopterigidae (cosmet moths) is a family of insects in the Lepidoptera order. These are small moths with narrow wings whose tiny larvae feed internally on the leaves, seeds, stems, etc of their host plants. There are about 1,500 described species. The family is most diverse in the Australian and Pacific region with about 780 species. [more]
Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths. Ths family contains over 110 genera with almost 700 known species, and many more species await description. Carpenter millers are nocturnal Lepidoptera found worldwide, except the Southeast Asian subfamily Ratardinae which is mostly active during the day. [more]
The Crambidae are the grass moth family of Lepidoptera (butterflies and moths). They are quite variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass-stems where they are inconspicuous, while other subfamilies include brightly colored and patterned insects which rest in wing-spread attitudes. [more]
Noctuoidea is the superfamily of noctuid (Latin "night owl") or "owlet" moths, and has the largest number of species described for any Lepidopteran superfamily. Its classification has not yet reached a satisfactory or stable state. The most recent classifications include only four families in the superfamily; Noctuidae, Oenosandridae, Doidae, and Notodontidae. The remaining four families listed here are presently all considered subfamilies within Noctuidae. [more]
Dalceridae is a small family of moths with 84 known species. They are mostly found in the Neotropical region with a few reaching the far south of the Nearctic region. [more]
Milkweed butterflies are a subfamily, Danainae, in the family Nymphalidae, or brush-footed butterflies. They lay their eggs on various milkweeds on which their larvae (caterpillars) feed. Historically, this group had been considered a separate family, Danaidae, and the tribes placed herein were sometimes considered distinct subfamilies in the Nymphalidae. [more]
The Depressariinae ? sometimes spelled "Depressiinae" in error ? are a subfamily of moths in the superfamily Gelechioidea. Like their relatives therein, their exact relationships are not yet very well resolved. It has been considered part of family Elachistidae sensu lato or treated as distinct gelechioid family Depressariidae, but more recently they are assumed to be closer to the Oecophorinae and included in an expanded Oecophoridae. [more]
Dioptinae is a subfamily of the moth family Notodontidae. [more]
The small Lepidopteran family Douglasiidae includes several species of moths whose adults are collectively called Douglas moths and whose larvae are leaf miners. The largest genus in the family is . [more]
The Elachistidae (grass-miner moths) are a family of small moths in the superfamily Gelechioidea. Some authors lump about 3,300 species in eight subfamilies here, but this arrangement almost certainly results in a massively paraphyletic and completely unnatural assemblage, united merely by symplesiomorphies retained from the first gelechioid moths. [more]
Epicopeiidae is a family of insects in the Lepidoptera order. They are known as Oriental Swallowtail Moths as they resemble Oriental Swallowtail butterflies so well. [more]
Epipyropidae is a small family of moths. This family and the closely related Cyclotornidae are unique among the Lepidoptera in that the larvae are ectoparasites, the hosts typically being fulgoroid planthoppers, thus the common name Planthopper Parasite Moths. [more]
Ethmiidae is a family of small moths in the superfamily Gelechioidea. It is sometimes included in the Elachistidae or the Oecophoridae as a subfamily Ethmiinae. [more]
Eupterotidae is a family of insects in the Lepidoptera order with more than 300 described species. [more]
Gelechiidae is a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the Gelechiidae's relationships with and delimitation against their relatives have been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (Pseudotsuga) is a host plant common to many species of the family, particularly of the genus Chionodes which is consequently more diverse in North America than usual for Gelechioidea. [more]
The geometer moths or Geometridae (from Greek geo ?? or ?a?a 'the earth' and metron ??t??? 'measure' ? refers to the larvae, which appear to "measure the earth" as they move in a looping fashion) are a family of the order Lepidoptera. A very large family, it has around 35,000 species of moths described, and over 1,400 species from 6 subclasses indigenous to North America. A well-known member is the Peppered Moth, Biston betularia, which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests. [more]
Glyphipterigidae is a family of small moths commonly known as sedge moths as the larvae of many species feed on sedges and rushes. More than 500 species have been described in the family. [more]
Heliodinidae is a family of small moths with slender bodies and narrow wings. Members of this family are found in all parts of the world. [more]
A family of primitive monotrysian moths in the order Lepidoptera, Heliozelidae are small, metallic day-flying moths with shiny smooth heads, In Europe the small adult moths (genera Antispila and Heliozela) are seldom noticed as they fly quite early in the Spring. The larvae are leaf miners and the vacated leaf mines are distinctive because the larva leaves a large hole at the end. [more]
The Hepialidae is a family of insects in the lepidopteran order. Moths of this family are often referred to as swift moths or ghost moths. [more]
A skipper or skipper butterfly is a butterfly of the family Hesperiidae. They are named after their quick, darting flight habits. There are more than 3500 recognized species of skippers and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America. [more]
Himantopteridae is a family of insects in the Lepidoptera order. [more]
Immoidea is a superfamily of pantropical moths containing only the family Immidae comprising ten genera with around 250 species, over half of them in the genus Imma. Many are brightly colored and diurnal. The position of this group is currently uncertain within the group Obtectomera. The larvae feed on the leaves of dicotyledons and conifers including Podocarpus (Dugdale et al. 1999). [more]
Incurvariidae is a family of small primitive monotrysian moths in the order Lepidoptera. There are twelve genera recognised (Davis, 1999). Many species are leaf miners and much is known of their hostplants, excluding Paraclemensia acerifoliella (Fitch). The most familiar species in Europe are perhaps Incurvaria masculella and Phylloporia bistrigella. The narrow wings are held tightly along the body at rest and some species have very long antennae. [more]
Lacturidae is a family of insects in the Lepidoptera order. Brighly colored tropical moths Lacturidae have been previously placed in Plutellidae, Yponomeutidae and Hyponomeutidae. [more]
The Lasiocampidae family of moths are also known as eggars, snout moths or lappet moths. There are over 2000 species worldwide, and probably not all have been named or studied. [more]
Lecithoceridae (long-horned moths) is a family of small moths. Although lecithocerids are found throughout the world, the great majority are found in the Indomalaya ecozone and the southern part of the Palaearctic ecozone. [more]
Libytheinae is the nymphalid subfamily of the snout butterflies, containing two valid genera and about 10 species, 6 in Libythea and 4 in Libytheana. The common name refers to the thick labial palps (pedipalps) that look like a "snout" in this subfamily. In older literature, this group was recognized as the family Libytheidae. They are medium-sized and typically a drab brown. The front legs are reduced in length and the ventral hindwings are cryptically colored in order to help in blend in with its surroundings. While at rest, the members of this subfamily keep their wings tightly closed in order to resemble dead leaves. [more]
Limacodidae or Euclidae is a family of moths in the superfamily Zygaenoidea or the Cossoidea; the placement is in dispute. They are often called slug moths because their caterpillars bear a distinct resemblance to slugs. They are also called cup moths because of the shape of their cocoons. [more]
The Lycaenidae are the second-largest family of butterflies, with about 6000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 40% of the known butterfly species. [more]
Lymantriidae is a family of moths. Many of its component species are referred to as "Tussock moths" of one sort or another. The caterpillar, or larval, stage of these species often has a distinctive appearance of alternating bristles and haired projections. Like other families of moths, many Tussock Moth caterpillars have urticating hairs (often hidden among longer, softer hairs) which can cause painful reactions if they come into contact with skin. [more]
Lyonetiidae is a family of moths with some 200 described species. These are small, slender moths, the wingspan rarely exceeding 1 cm. The very narrow forewings, held folded backwards covering the hindwings and abdomen, often have pointed apices noticeably up- or down-turned. The larvae are leaf miners. [more]
Megalopygidae is the technical name of a group of insect species known generally as crinkled flannel moths, or simply Flannel Moths. They occur in North America (11 species) and the New World tropics. The larvae are called Puss Caterpillars, and with their long hairs, resemble cotton balls. They have venomous spines that can cause a painful sting and inflammation lasting for several days. In some cases, the sting may cause headache, nausea, and shock-like symptoms. Perhaps the most notorious for stinging is the caterpillar of Megalopyge opercularis. [more]
Metachandidae is a small family of moths containing a single genus, Metachanda. [more]
Micropterigoidea is the superfamily of "mandibulate archaic moths", all placed in the single family Micropterigidae, containing currently about 20 living genera. They are considered the most primitive extant lineage of Lepidoptera (Kristensen, 1999). [more]
Momphidae (mompha moths) is a family of moths with some 115 described species. These tend to be rather small moths with a wingspan of up to 21 mm. The wings are held folded over the body at rest. The larvae are concealed feeders, either as leaf miners or within seeds or stems. [more]
Nepticulidae is a family of very small moths with a worldwide distribution. They are characterised by eyecaps over the eyes (see also Opostegidae, Bucculatricidae, Lyonetiidae). These pigmy moths or midget moths, as they are commonly known, include the smallest of all living moths, with a wingspan that can be as little as 3 mm. in the case of the European Pigmy Sorrel Moth, but more usually 3.5?10 mm. The wings of adult moths are narrow and lanceolate, sometimes with metallic markings, and with the venation very simplified compared to most other moths. [more]
The Noctuidae or owlet moths are a family of robustly-built moths that includes more than 35,000 known species out of possibly 100,000 total, in more than 4,200 genera. They constitute the largest family in the Lepidoptera. [more]
Nolidae is a family of moths with about 1,400 described species worldwide. They are mostly small with dull coloration, the main distinguishing feature being tufts of raised scales on the forewings (the group is sometimes known as tuft moths). The larvae also tend to have muted colors and tufts of short hairs. [more]
Notodontidae is a family of moths with approximately 3,800 known species. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas, especially in the New World (Miller, 1992). The Thaumetopoeidae (processionary moths) are sometimes included here as a subfamily. [more]
The Nymphalidae is a family of about 5,000 species of butterflies which are distributed throughout most of the world. These are usually medium sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colorful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies. Many species are brightly colored and include popular species such as the emperor, admirals, tortoiseshells and fritillaries. However, the underwings are in contrast often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterfly disappear into its surroundings. [more]
Oecophoridae (concealer moths) is a family of small moths in the superfamily Gelechioidea. The phylogeny and systematics of gelechoid moths are still not fully resolved, and the circumscription of the Oecophoridae is strongly affected by this. [more]
Opostegidae or "white eyecap moths" is a family of insects in the Lepidoptera order that is characterised by particularly large eyecaps over the compound eyes (see also Nepticulidae, Bucculatricidae, Lyonetiidae). Opostegidae are most diverse in the New World tropics (83 described species, representing 42% of the world total). [more]
Pantheidae is a family of Lepidoptera. Mostly, it is classified as a subfamily of Noctuidae, under the name Pantheinae. [more]
Swallowtail butterflies are large, colorful butterflies that form the family Papilionidae. There are over 550 species, and though the majority are tropical, members of the family are found on all continents except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of Australia (genus Ornithoptera). [more]
The Pieridae are a large family of butterflies with about 76 genera containing approximately 1,100 species, mostly from tropical Africa and Asia. Most pierid butterflies are white, yellow or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. [more]
Plutellidae is a family of moths. Some authors consider this family to be a subfamily of Yponomeutidae. [more]
Prodoxidae is a family of primitive monotrysian Lepidoptera. Some of these small-to-medium sized moths are day flying, like Lampronia capitella, known to European gardeners as the "Currant Shoot Borer". Others occur in Africa and Asia.Tetragma gei feeds on Mountain Avens Geum triflorum in USA. Greya politella lay eggs in the flowers of Saxifragaceae there. The last five genera listed here are confined to dry areas of the United States. occurs in Chile and Argentina (Nielsen and Davis, 1985), but all other prodoxid moth genera have a northern distribution. The enigmatic genus Tridentaforma is sometimes placed here and assumed to be close to Lampronia, while other authors consider it incertae sedis among the closely related family Adelidae. [more]
The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths). The bagworm family is fairly small, with about 600 species described. Bagworm species are found globally, with some, such as the Snailcase Bagworm (Apterona helicoidella), settling continents where they are not native in modern times. [more]
The Pterophoridae or plume moths are a family of Lepidoptera with unusually modified wings. Though they belong to the Apoditrysia like the larger moths and the butterflies, unlike these they are tiny and were formerly included among the assemblage called "Microlepidoptera". [more]
The Pyralidae or snout moths are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many (particularly older) classifications, the grass moths (Crambidae) are included in the Pyralidae as a subfamily, making the combined group one of the largest families in the Lepidoptera. The latest review by Munroe & Solis, in Kristensen (1999) retains the Crambidae as a full family of pyraloidea. [more]
The Riodinidae (or metalmarks) are a family of butterflies. The common name "metalmarks" refers to the small metallic-looking spots commonly found on their wings. There are approximately 1,000 species of metalmark butterflies in the world. Although mostly neotropical in distribution, the family is represented both in the Nearctic and the Old World. [more]
The Saturniidae, commonly known as saturniids, are among the largest and most spectacular of the moths. They form a family of Lepidoptera, with an estimated 2,300 described species worldwide. The Saturniidae include such Lepidoptera as the giant silkmoths, royal moths and emperor moths. [more]
Satyrinae, the satyrines or satyrids, commonly known as the Browns, is a subfamily of the Nymphalidae (brush-footed butterflies). They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. It is estimated that the true number of the Satyrinae species may exceed 2,400. [more]
Schreckensteinioidea is a superfamily in the insect order Lepidoptera containing a single family, Schreckensteiniidae, or "bristle-legged moths", because of the stout spines on the hindlegs. The relationships of this family within the group Apoditrysia are currently uncertain. One of the species, the Blackberry Skeletoniser Schreckensteinia festaliella, is widespread and common across Europe and has been introduced as a biological control to Hawaii, whilst three species of Corsocasis occur in South East Asia (Dugdale et al., 1999). [more]
Scythrididae (flower moths) is a family of small moths in the superfamily Gelechioidea. The family is sometimes included in the as a subfamily Scythridinae, but the Xyloryctidae themselves have sometimes been included in the Oecophoridae as subfamily. Scythrididae adults are smallish to mid-sized moths, which when at rest appear teardrop-shaped. [more]
The Sesiidae or clearwing moths are family of the Lepidoptera in which the wings partially have hardly any of the normal lepidopteran scales, leaving them transparent. The bodies are generally striped with yellow, red or white, sometimes very brightly, and they have simple antennae. The general appearance is sufficiently similar to a wasp or hornet to make it likely that the moths gain a reduction in predation by Batesian mimicry. This enables them to be active in daylight. They are commonly collected using pheromone lures. Worldwide there are 151 genera, 1370 species , and 50 subspecies. Most of these occur in the tropics, but there are many species in the Holarctic region. [more]
Somabrachyidae is a family of moth in the order Lepidoptera. [more]
Sphingidae is a family of moths (Lepidoptera), commonly known as hawk moths, sphinx moths and hornworms, that includes about 1,450 species. It is best represented in the tropics but there are species in every region. They are moderate to large in size and are distinguished among moths for their rapid, sustained flying ability. The narrow wings and streamlined abdomen are adaptations for rapid flight. [more]
The Symmocidae are a family of moths in the superfamily Gelechioidea. These small moths are found mainly in the Palearctic and Africa. [more]
Thyrididae is the picture-winged leaf moths family of moths in the Lepidoptera order. They alone make up the Thyridoidea superfamily, which is sometimes included in the Pyraloidea (though this is not supported by cladistic analysis. [more]
Tineidae is a family of moths in the order Lepidoptera. Collectively, they are known as fungus moths or tineid moths. The family contains considerably more than 3,000 species in over 300 genera. Most of the tineid moths are small or medium-sized, with wings held roofwise over the body at rest. They are particularly common in the Palaearctic, but many occur elsewhere, and some are found very widely as introduced species. [more]
Tischerioidea is the superfamily of "trumpet" leaf miner moths. This is one candidate as the sister group (see also Palaephatoidea) of the bulk of Lepidoptera, the Ditrysia (Davis, 1999; Wiegmann et al., 2002), and they have a monotrysian type of female reproductive system. The superfamily contains just one family and traditionally one genus, Tischeria, but currently three genera are recognised, widespread across the World including South America (Davis, 1986), except for Australasia (Puplesis and Diskus, 2003). These small moths are leaf-miners in the caterpillar stage, feeding mainly on Fagaceae (Tischeria and Coptotriche), Asteraceae and Malvaceae (Astrotischeria), and some also on Rhamnaceae, Tiliaceae and Rosaceae. [more]
Tortricidae is a family of moths, commonly known as tortrix moths, in the order Lepidoptera. Tortricidae is a large family with over 10,350 species described, and is the sole member of the superfamily Tortricoidea. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back producing a rather rounded profile. [more]
The Uraniidae are a family of moths containing four subfamilies, ninety genera, and roughly seven-hundred species. The family is distributed throughout the tropics of Americas, Africa and Indo-Australia. Some of the tropical species are known for their bright, butterfly-like colors and are called sunset moths (for example Chrysiridia rhipheus). Such moths are apparently toxic and the bright colors are a warning to predators. [more]
The family Yponomeutidae are known as the ermine moths, with several hundred species, most of them in the tropics. The larvae tend to form communal webs, and some are minor pests in agriculture, forestry, and horticulture. Some of the adults are very attractive. Adult moths are minor pollinators. [more]
The Zygaenidae moths are a family of Lepidoptera. The majority of zygaenids are tropical, but they are nevertheless quite well represented in temperate regions. There are about 1000 species. Various species are commonly known as Burnet or Forester moths, often qualified by the number of spots, although other families also have 'foresters'. They are also sometimes called Smoky moths. [more]
At least 3,986 species and subspecies belong to the Family Zygaenidae.
