Aderidae

Aderidae, the ant-like leaf beetles, is a family of beetles that bear some resemblance to ants. The family consists of about 1,000 species in about 50 genera, of which most are tropical, although overall distribution is worldwide. [more]

Aegialiidae

[more]

Aglycyderidae

Aglycyderini are a tribe of belids, primitive weevils of the family Belidae. Like in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae). They occur only on the Pacific Islands and in the Macaronesian region.. [more]

Agyrtidae

Agyrtidae or primitive carrion beetles are a small family of polyphagan beetles They are found in mostly temperate areas of the northern hemisphere and in New Zealand. They are feeding on decaying organic material. [more]

Alleculidae

[more]

Amphizoidae

Amphizoa is a genus of beetles, placed in its own family, Amphizoidae. It comprises six species, three from western North America and three from China. The vernacular name "trout-stream beetle" comes from the original finding of A. insolens and A. lecontei in high mountain streams, although other species occur at lower elevation. They are notable as a possible intermediate stage between terrestrial and aquatic beetles; while living in the water, they are not good swimmers and physically resemble ground beetles more than other types of water beetle. [more]

Anobiidae

Anobiidae is a family of beetles. The larvae of a number of species tend to bore into wood, earning them the name "woodworm" or "wood borer". A few species are pests, causing damage to wooden furniture and house structures, notably the death watch beetle, Xestobium rufovillosum, and the common furniture beetle, Anobium punctatum. [more]

Anthicidae

Anthicidae is a family of beetles, sometimes called ant-like flower beetles or ant-like beetles that resemble ants. The family consists of over 3,000 species in about 100 genera. [more]

Anthribidae

Anthribidae is a family of beetles also known as fungus weevils. The antennae are not elbowed, may occasionally be longer than the body and thread-like, and can be the longest of any members of Curculionoidea. As in the Nemonychidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting. [more]

Attelabidae

The Attelabidae or leaf-rolling weevils are a widespread family of weevils. There are more than 2000 species. They are included within the primitive weevils, because of their straight antennae, which are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. [more]

Aulonocnemidae

[more]

Belidae

Belidae is a family of weevils, called belids or primitive weevils because they have straight antennae, unlike the "true weevils" or Curculionidae which have elbowed antennae. They are sometimes known as "cycad weevils", but this properly refers to a few species from the genera and Rhopalotria. [more]

Belohinidae

Belohina inexpectata is a polyphagan beetle and the sole member of family Belohinidae. It is endemic to southern Madagascar. Only a few specimens of this species are known. [more]

Boridae

The family Boridae is a small group of beetles with no vernacular common name, though recent authors have coined the name conifer bark beetles. [more]

Bostrichidae

The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles or horned powderpost beetles. The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. An exception is the powderpost beetles from the subfamily Lyctinae. [more]

Brachypsectridae

Brachypsectridae is a family of beetles commonly known as the Texas beetles. There is only one genus, . The type species, Brachypsectra fulva (LeConte, 1874), occurs in North America. There are three other species which occur in southern India, Singapore and northwestern Australia. Two other extant and fossil species have been described from the Dominican Republic. [more]

Brachypteridae

[more]

Brenthidae

[more]

Brentidae

Brentidae is a cosmopolitan family of primarily xylophagous beetles also known as straight-snouted weevils. The concept of this family has been recently expanded with the inclusion of three groups formerly placed in the Curculionidae; the subfamilies , Cyladinae, and Nanophyinae, as well as the Ithycerinae, previously considered a separate family. They are most diverse in the tropics, but occur throughout the temperate regions of the world. They are among the families of weevils that have non-elbowed antennae, and tend to be elongate and flattened, though there are numerous exceptions. [more]

Bruchidae

The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living for most of their lives inside a single seed. The family includes about 1,350 species found worldwide. [more]

Buprestidae

Buprestidae is a family of beetles, known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. The family is among the largest of the beetles, with some 15,000 species known in 450 genera. In addition, almost 100 fossil species have been described. [more]

Byrrhidae

Byrrhidae, the pill beetles, is a family of beetles in the superfamily Byrrhoidea. [more]

Byturidae

Byturidae, also known as Fruitworms is a family of beetles, in the suborder Polyphaga. The larvae develop in fruits. Byturus unicolor affects species of Rubus and Geum, the larvae of Raspberry beetle raspberry plants. [more]

Callirhipidae

[more]

Cantharidae

The soldier beetles, Cantharidae, are relatively soft-bodied, straight-sided beetles, related to the Lampyridae or firefly family, but being unable to produce light. They are cosmopolitan in distribution. One common British species is bright red, reminding people of the red coats of soldiers, hence the common name. A secondary common name is leatherwing, obtained from the texture of the wing covers. [more]

Carabidae

Ground beetles are a large, cosmopolitan family of beetles, Carabidae, with more than 40,000 species worldwide, approximately 2,000 of which are found in North America and 2,700 in Europe. [more]

Catopidae

[more]

Cavognathidae

Cavognathidae is a family of beetles, in the suborder Polyphaga. [more]

Cebrionidae

[more]

Cephaloidae

[more]

Cerambycidae

The longhorn beetles (Cerambycidae; also known as long-horned beetles or longicorns) are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., Neandra brunnea, figured below) and such species can be difficult to distinguish from related beetle families such as Chrysomelidae. The family is large, with over 20,000 species described, slightly more than half from the Eastern Hemisphere. Several are serious pests, with the larvae boring into wood, where they can cause extensive damage to either living trees or untreated lumber (or, occasionally, to wood in buildings; the old-house borer, Hylotrupes bajulus, being a particular problem indoors). A number of species mimic ants, bees, and wasps, though a majority of species are cryptically colored. The rare titan beetle (Titanus giganteus) from nor theastern South America is often considered the largest (though not the heaviest, and not the longest including legs) insect, with a maximum known body length of just over 16.7 centimetres (6.6 in).

Cerophytidae

[more]

Cerylonidae

Cerylonidae is a family of beetles, in the suborder Polyphaga.The Cerylonidae are a family of small to minute beetles (usually 2 mm. 01- less) which occur most commonly in forest litter and under bark. At present, there are about 40 genera and over 300 described species known from all of the major zoogeographic regions. Crowson (1955) first recognized the Cerylonidae as an independent clavicorn family, including the cerylonines and murmidiines, as well as Euxes- tus and its allies; but these groups have been treated as tribes of the heteromerous family Colydiidae by both Hetschko (1930) and Ar- nett (1968). In their world generic revision of the family, Sen Gupta and 'Crowson (1973) added Anommatus Wesmael, Abromus Reitter, and Ostomopsis Scott, while transferring Eidoreus Sharp (== Eupsilob'ws Casey) to the Endomychidae. The present paper consists of a revision of the 10 genera and 18 species of Cerylonidae occurring in America north of Mexico. With respect to the compo- sition of the family and that of its major subordinate groups, we have followed the classification presented by Sen Gupta and Crowson; the interrelationships among the subgroups, however, are still obscure, so we have treated the Euxestinae, Anommatinae, Metaceqloninae (not North American), Murrnidiinae, Ostomopsinae, and Cerylon- inae as independent subfamilies. The following abbreviations have been used in keys and descrip- tions: PL - pronotal length, PW - pronotal width, EL - elytral length, EW - elytral width, and TL -sum of PL and EL. The word "length" refers to the total length, including the head, and is 'Published with the aid of a grant from the Museum of Comparative Zoology.

Cetoniidae

Flower chafers are a group of scarab beetles, comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed. [more]

Cicindelidae

The tiger beetles are a large group of beetles known for their aggressive predatory habits and running speed. The fastest species of tiger beetle can run at a speed of 9 km/h (5.6 mph), which, relative to its body length, is about 22 times the speed of former Olympic sprinter Michael Johnson, the equivalent of a human running at 480 miles per hour (770 km/h). As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics. [more]

Ciidae

The minute tree-fungus beetles, family Ciidae, are a sizeable group of beetles which inhabit Polyporales bracket fungi or coarse woody debris[]. Most numerous in warmer regions, they are nonetheless widespread and a considerable number of species occur as far polewards as Scandinavia for example. [more]

Clambidae

Cneoglossidae

Cneoglossidae is a family of beetles, in the large suborder Polyphaga.
It contains nine species in a single genus: [more]

Coccinellidae

Coccinellidae is a family of beetles, known variously as ladybirds (UK, Ireland, Australia, Sri Lanka, Pakistan, South Africa, New Zealand, India, Malta, some parts of Canada and the US), or ladybugs (North America). Scientists increasingly prefer the names ladybird beetles or lady beetles as these insects are not true bugs. Lesser-used names include God's cow, ladycock, lady cow, and lady fly. [more]

Colydiidae

Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family, but have recently been moved into the Zopheridae , where they constitute the bulk of the diversity of the new composite family, with about 140 genera worldwide. There is not much known about the biology of these beetles. Most feed on fungi, others are carnivores and feed on arthropods. [more]

Cryptophagidae is a family of beetles with representatives found in all ecozones. Only around 800 species have been described but it seems certain that many others await discovery. Members of this family are commonly called silken fungus beetles and both adults and larvae appear to feed exclusively on fungi although in a wide variety of habitats and situations (e.g. rotting wood, shed animal fur/feathers). These beetles are generally small to very small, usually with a basically oval body shape with a slight "waist". [more]

Cucujidae

The Cucujidae, sometimes called flat bark beetles are a family of distinctively flat beetles found worldwide under the bark of dead and live trees. The family consists of about 40 species in four genera. [more]

Cupedidae

Cupedidae is a small family of beetles, notable for the square pattern of "windows" on their elytra (hard forewings), which gives the family their common name of reticulated beetles. [more]

Curculionidae

Curculionidae is the family of the "true" weevils (or "snout beetles"). It was formerly recognized in 1998 as the largest of any animal family, with over 40,000 species described worldwide at that time. Today, it is still one of the largest known. [more]

Cybocephalidae

Dermestidae

Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are approximately 500 to 700 species worldwide. They can range in size from 1?12 mm. Key characteristics for adults are round oval shaped bodies covered in scales or setae. The (usually) clubbed antennae fit into deep grooves. The hind femora also fit into recesses of the coxa. Larvae are scarabaeiform and also have setae. [more]

Derodontidae

Derodontidae is a family of beetles, in its own superfamily, Derodontoidea, sometimes known as tooth-necked fungus beetles. There are 38 species in 4 genera and 3 subfamilies. Beetles of this family are small, between 2 and 6 mm in length, with spiny margins on their pronotum (part of the thorax) that give them their name. The genus, Laricobius, lacks these spines. They have two ocelli on the top of their heads. [more]

Diphyllostomatidae

The false stag beetles (Diphyllostoma) are a group of three species of rare beetles known only from California. Almost nothing is known of their life history beyond that the adults are diurnal and females are flightless; larvae have not been observed. [more]

Dryopidae

[more]

Dynastidae

The Rhinoceros Beetles or Rhino Beetles are a subfamily (Dynastinae) of the scarab beetle family (Scarabaeidae). Other common names ? some for particular groups of rhino beetles ? are for example Hercules beetles, unicorn beetles or horn beetles. There are over 300 known species of rhino beetles. [more]

Dytiscidae

Dytiscidae ? based on the Greek dytikos (d?t????), "able to dive" ? are the predaceous diving beetles, a family of water beetles. They are about 25 mm (one inch) long on average, though there is much variation between species. Dytiscus latissimus, the largest[], can grow up to 45 mm long. Most are dark brown, blackish or dark olive in color with golden highlights in some subfamilies. They have short, but sharp mandibles. Immediately upon biting they deliver digestive enzymes. The larvae are commonly known as water tigers. The family has not been comprehensively cataloged since 1920, but is estimated to include about 4,000 species in over 160 genera. [more]

Elateridae

The family Elateridae is commonly called click beetles (or "typical click beetles" to distinguish them from the related Cerophytidae and ), elaters, snapping beetles, spring beetles or "skipjacks". They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few closely related families in which a few members have the same mechanism, but all elaterids can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" which can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America. [more]

Elmidae

Elminthidae

[more]

Endomychidae

Endomychidae, or handsome fungus beetles is a family of beetles with representatives found in all ecozones.There are around 120 genera and 1300 species. As the name suggests Endomychidae feed on fungi. [more]

Erirhinidae

[more]

Erotylidae

Erotylidae is the pleasing fungus beetles, is a family of beetles containing over 100 genera. In the present circumscription, it includes the subfamilies , Encaustinae, Erotylinae, Megalodacninae, and Tritominae. In other words, the narrowly-circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. They feed on plant and fungal matter; some are important pollinators (e.g. of the ancient cycads), while a few have gained notoriety as pests of some significance. Sometimes, useful and harmful species are found in one genus, e.g. Pharaxonotha. Most pleasing fungus beetles are inoffensive animals of little significance to humans however. [more]

Euchiridae

[more]

Eucinetidae

Eucinetidae is a family of beetles, notable for their large that cover much of the first ventrite of the abdomen, sometimes called plate-thigh beetles. The family is small for beetles, with about 37 species in nine genera, but are found worldwide. [more]

Eucnemidae

[more]

Eulichadidae

[more]

Eurhynchidae

[more]

Georyssidae

Georissus, also called minute mud-loving beetles, is the only genus in the beetle family Georissidae (or Georyssidae). They are tiny insects living in wet soil, often near water. Found on every continent except Antarctica. [more]

Geotrupidae

Geotrupidae (from Greek geos[], earth, and trypetes, borer) is a family of beetles in the order Coleoptera. They are commonly called dor beetles or earth-boring dung beetles. Most excavate burrows in which to lay their eggs. They are typically detrivores, provisioning their nests with leaf litter (often moldy), but are occasionally coprophagous, similar to dung beetles. The eggs are laid in or upon the provision mass and buried, and the developing larvae feed upon the provisions. The burrows of some species can exceed 2 metres in depth. [more]

Glaphyridae

Glaphyridae is a family of beetles, commonly known as The bumble bee scarab beetles. There are eight genera with about 80 species distributed worldwide. [more]

Glaresidae

Glaresis is a genus of beetles, sometimes called "enigmatic scarab beetles", in its own family, the Glaresidae. It is closely related to scarab beetles. Although its members occur in arid and sandy areas worldwide (except Australia), only the nocturnal adults have ever been collected (typically at lights), and both the larvae and biology of Glaresis are as yet unknown. Due to their narrow habitat associations, a great number of these species occur in extremely limited geographic areas, and are accordingly imperiled by habitat destruction. [more]

Gyrinidae

The whirligig beetles are a family (Gyrinidae) of water beetles that usually swim on the surface of the water if undisturbed, though they swim actively underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. [more]

Haliplidae

The Haliplidae are a family of water beetles who swim using an alternating motion of the legs. They are therefore clumsy in water (compared e.g. with the Dytiscidae or Hydrophilidae), and prefer to get around by crawling. The family consists of about 200 species in 5 genera, distributed wherever there is freshwater habitat; it is the only extant member of superfamily Haliploidea. They are also known as crawling water beetles or haliplids. [more]

Harpalidae

Heteroceridae

The Heteroceridae, or variegated mud-loving beetles, are a widespread and relatively common family of beetles. They occur on every continent except for Antarctica. [more]

Histeridae

Histeridae is a family of beetles commonly known as Clown beetles or Hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their elbowed antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other Hister beetles, they must be isolated when collected. [more]

Homalisidae

[more]

Hybosoridae

Hybosoridae, sometimes known as the scavenger scarab beetles, is a family of scarabaeiform beetles. The 210 species in 33 genera occur widely in the tropics, but little is known of their biology. [more]

Hydraenidae

Hydraenidae is a family of very small aquatic beetles with a worldwide distribution. These beetles are generally 1-3 mm in length (although some species reach 7 mm) with clubbed antennae. They do not swim well and are generally found crawling in marginal vegetation. Most are phytophagous but a few saprophagous and predatory species are known. [more]

Hydrophilidae

Hydrophilidae , also called water scavenger beetles, is a family of chiefly aquatic beetles. Aquatic hydrophilids are notable for their long , which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae). Some of these formerly-included groups are primarily terrestrial or semi-aquatic. [more]

Lagriidae

[more]

Lamingtoniidae

[more]

Lampyridae

Lampyridae is a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their conspicuous crepuscular use of bioluminescence to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically-produced light from the lower abdomen may be yellow, green, or pale-red, with wavelengths from 510 to 670 nanometers. [more]

Latridiidae

Latridiidae is a family of tiny, little-known beetles commonly called minute brown scavenger beetles. The number of described species currently stands at around 1050 in 29 genera but the number of species is undoubtedly much higher. [more]

Leiodidae

Leiodidae is a family of beetles with around 3800 described species found worldwide. Members of this family are commonly called round fungus beetles due to the globular shape of many species, although some are more elongated in shape. They are generally small or very small beetles (less than 10 mm in length) and many (but not all) species have clubbed antennae. [more]

[more]

Lycidae

Lycidae is a family in the beetle order Coleoptera, members of which are commonly called net-winged beetles. [more]

Lyctidae

Powderpost beetles are a group of seventy species of woodboring beetles classified in the insect subfamily Lyctinae. These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax, powderpost beetles do not, making their heads more visible. In addition to this, their antennae have two-jointed clubs. They are considered pests and attack deciduous trees, over time reducing the wood to a powdery dust. The damage caused by longhorn beetles (family Cerambycidae) is often confused with that of powderpost beetles, but the two groups are unrelated. Their larvae are white and C-shaped. [more]

Lymexylidae

The Lymexylidae, or ship-timber beetles, are a family of wood-boring beetles, and the sole member of the superfamily Lymexyloidea. [more]

Many are conspicuous and some aposematically colored, announcing their toxicity to would-be predators. [more]

Melolonthidae

[more]

Melyridae

Melyridae (common name: soft-wing flower beetles) are a family of beetles of the superfamily Cleroidea. The family Melyridae contains 520 species in 58 genera in North America. Most are elongate-oval, soft-bodied beetles 10 mm long or less. Many are brightly colored with brown or red and black. Some melyrids () have peculiar orange structures along the sides of the abdomen, which may be everted and saclike or withdrawn into the body and inconspicuous. Some melyrids have the two basal antennomeres greatly enlarged. Most adults and larvae are predaceous, but many are common on flowers. The most common North American species belong to the genus Collops (Malachiinae); C. quadrimaculatus is reddish, with two bluish black spots on each elytron. Batrachotoxins are found in them. [more]

Microsporidae

Sphaerius is a genus of beetle, comprising 23 species, which are the only members of the family Sphaeriusidae. They are typically found along the edges of streams and rivers, where they feed on algae, occurring on all continents except Antarctica. Only 3 species occur in the United States. [more]

Monommidae

Monommatinae is a subfamily (or sometimes only considered a tribe) of beetles with no vernacular common name, though recent authors have coined the name opossum beetles. They have been treated historically as a family (sometimes spelled Monommidae), but have recently been placed into the Zopheridae. There are some 15 genera in this group, commonly found in association with plants in the family Agavaceae. [more]

Monotomidae

[more]

Mordellidae

Mordellidae is a family of beetles commonly known as tumbling flower beetles for the typical irregular movements they make when escaping predators, or as pintail beetles due to their abdominal tip which aids them in performing these tumbling movements. Worldwide, there are about 1500 species. [more]

Mycetophagidae

Mycetophagidae or The hairy fungus beetles is a family of beetles, in the large suborder Polyphaga. The different species are between 1.0 - 6.5 mm in length. The larvae and adults live in decaying leaf litter, fungi and under bark. Most species feed on fungi (hence the name). Worldwide, there are about 18 genera which 200 species. [more]

Mycteridae

[more]

Nanophyidae

[more]

Nemonychidae

Nemonychidae is a small family of weevils, placed within the primitive weevil group because they have straight rather than elbowed antennae. They are often called pine flower weevils. As in the Anthribidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting. Nemonychidae have all ventrites free, while Anthribidae have ventrites 1-4 connate or partially fused. Nemonychidae lack lateral carinae on the pronotum, while these are usually present, though may be short, in Anthribidae. [more]

Noteridae

Noteridae is a family of water beetles closely related to the Dytiscidae, and formerly classified with them. They are mainly distinguished by the presence of a distinctive "noterid platform" underneath, in the form of a plate between the second and third pair of legs. The family consists of about 230 species in 12 genera, and is found worldwide, more commonly in the tropics. They are sometimes referred to as burrowing water beetles. [more]

Ochodaeidae, sometimes known as the sand-loving scarab beetles, is a small but widely-distributed family of scarabaeiform beetles. [more]

Oedemeridae

The family Oedemeridae is a cosmopolitan group of beetles commonly known as false blister beetles, though some recent authors have coined the name pollen-feeding beetles. There are some 100 genera and 1,500 species in the family, mostly associated with rotting wood as larvae, though adults are quite common on flowers. [more]

Passalidae

Passalidae is a family of beetles known variously as "bessbugs", "bess beetles", "betsy beetles" or "horned passalus beetles". Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20?43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles.

Platypodidae

Ambrosia beetles are beetles of the weevil subfamilies Scolytinae and Platypodinae (Coleoptera, Curculionidae), which live in nutritional symbiosis with ambrosia fungi and probably with bacteria. The beetles excavate tunnels in dead trees in which they cultivate fungal gardens, their sole source of nutrition. After landing on a suitable tree, an ambrosia beetle excavates a tunnel in which it releases spores of its fungal symbiont. The fungus penetrates the plant's xylem tissue, digests it, and concentrates the nutrients on and near the surface of the beetle gallery. The majority of ambrosia beetles colonize xylem (sapwood and/or heartwood) of dying or recently dead trees. Species differ in their preference for different parts of trees, different stages of deterioration, in the shape of their tunnels (?galleries?). However, the majority of ambrosia beetles are not specialized to any taxonomic group of hosts, unlike most phytophagous organisms including the closely related bark beetles. [more]

Pleocomidae

The rain beetles are a group of beetles found in the far west of North America. They spend most of their lives underground, emerging in response to rain or snow, thus the common name. Formerly classified in the Geotrupidae, they are currently assigned to their own family Pleocomidae, considered the sister group to all the remaining families of Scarabaeoidea. The family contains a single extant genus, Pleocoma, and one extinct genus, Cretocoma, described in 2002 from Late Cretaceous deposits in Mongolia. [more]

Pselaphidae

Pselaphinae is a subfamily of small (usually less than 2.5 mm long) beetles. The group was originally regarded as a separate family, named Pselaphidae. Newton and Thayer (1995) placed them in the Omaliine group of the family Staphylinidae, based on shared morphological characters. [more]

Psephenidae

Water-penny beetles are a family (Psephenidae) of aquatic beetles. The young, which live in water, resemble pennies. The larvae feed off of algae, larvae, and feces. The presence of water penny larvae in a stream can be used as a test for the quality of the water. Among the pollution sensitivity categories sensitive, somewhat-sensitive, and tolerant; water pennies belong to the sensitive category. They cannot live in habitats where rocks acquire a thick layer of algae, fungi, or inorganic sediment. Therefore, their presence along with other diverse phyla signifies good quality water. They are around 6 to 10 millimeters in length. [more]

Pterogeniidae

Ptinidae

Spider beetles are the approximately 500 species of beetles in the subfamily Ptininae of the family Anobiidae. They are sometimes considered a family in their own right, which is then called Ptinidae. Spider beetles have round bodies with long, slender legs, and lack wings. They are generally 1?5 mm long. Both the larvae and the adults are scavengers. They reproduce at the rate of two to three generations per year. [more]

Pyrochroidae

Fire-colored beetles are the beetles of the Pyrochroidae family, which includes the red Cardinal beetles. This family contains some 150 species. Many species in the subfamily ve comb- or antler-like antennae. This family also now includes most former members of the defunct family Pedilidae. [more]

Scarabaeidae

The family Scarabaeidae as currently defined consists of over 30,000 species of beetles worldwide. The species in this large family are often called scarabs or scarab beetles. The classification of this family is fairly unstable, with numerous competing theories, and new proposals appearing quite often. It is probable that many of the subfamilies listed here will no longer be recognized very much longer, as they will likely be reduced in status below subfamily rank, or elevated to family status (the latter is most likely, e.g., with the family "Melolonthidae" already appearing in some recent classifications). Other families have been removed recently, and are nearly universally accepted (e.g., Pleocomidae, Glaresidae, Glaphyridae, Ochodaeidae, Geotrupidae, ) [more]

Scolytidae

A bark beetle is one of approximately 220 genera with 6,000 species of beetles in the subfamily Scolytinae. Traditionally, this was considered a distinct family Scolytidae, but now it is understood that bark beetles are in fact very specialized members of the "true weevil" family (Curculionidae). Well-known species are members of the type genus Scolytus - namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce Ips Ips typographus. A tiny bark beetle?the coffee berry borer, Hypothenemus hampei is a major pest of coffee around the world. [more]

Zopheridae is a family of beetles that has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both considered subfamilies within the Zopheridae. There are over 100 genera in the redefined family, and hundreds of species worldwide. There is no vernacular common name for the new family, though some of the constituent subfamilies have their own, including the ironclad beetles, and the cylindrical bark beetles. [more]

At least 125 species and subspecies belong to the Family Zopheridae.
