Description

Family Nymphalidae

'The Nymphalidae are members of the Superfamily Papilionoidea, the true butterflies. Distributed worldwide, butterflies of this family are especially rich in the tropics. They are highly variable, and there are more species in this family than in any other. Adults vary in size from small to large, and their front legs are reduced, unable to be used for walking. Wing shape is also highly variable: some species have irregular margins (anglewings and commas), and others have long taillike projections (daggerwings). Browns, oranges, yellows, and blacks are frequent colors, while iridescent colors such as purples and blues are rare. Adults of some groups are the longest-lived butterflies, surviving 6-11 months. Adult feeding behavior depends on the species, where some groups primarily seek flower nectar while others only feed on sap flows , rotting fruit, dung, or animal carcasses. Males exhibit perching and patrolling behaviors when seeking mates. Egg-laying varies widely, as some species lay eggs in clustsers, others in columns, and others singly. Caterpillar appearance and behavior vary widely. Brushfoots overwinter as larvae or adults.

Subfamily Nymphalinae

Brushfoots are the most prevalent members of the Family Nymphalinae. Distributed worldwide, this is a diverse group that contains several tribes , each with somewhat different structural and biological features. Adults of North American species are predominantly orange, brown, and black. Wing shape and mating systems are variable. Most checkerspots and crescentspots patrol for mates, while the remainder of groups exhibit either perching or perching and patrolling . Migration varies widely; some strong migrants are found in the lady butterflies, tortoiseshells, and anglewings, while other species are local in occurrence. Most species limit their host plants to a few species, but the Painted Lady has one of the widest host palettes of all butterflies. Eggs are laid singly or clustered in groups, and caterpillars be found feeding alone or communally. Brushfoots overwinter as young caterpillars or hibernating adults.[2]

Habitat

Biome: Terrestrial [3].

Ecology: This species replaces the Small Tortoiseshell (A. urticae) on the Islands of Corsica and Sardinia. It may be found in nearly all habitats but only in mountainous area at altitudes higher than 700 m. The larval foodplant is Stinging Nettle (Urtica dioica). It is double-generationed. Detailed habitat descriptions are not available.[3].
