|Genus:|| Aglais |
Aglais is a Holarctic genus of brush-footed butterflies, containing the tortoiseshells. This genus is sometimes indicated as a subgenus of Nymphalis or simply being an unnecessary division from the nymphalis genus,which also includes tortoiseshells, but it is usually considered to be separate. This proposed separate genus is also consider “brushfooted butterflies” historically together with the other or separate nymphalis species.
The Nymphalidae are the largest family of butterflies with more than 6,000 species distributed throughout most of the world, belonging to the superfamily Papilionoidea. These are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings 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 butterflies blend into their surroundings.
Aglais io, the European peacock, more commonly known simply as the peacock butterfly, is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. It was formerly classified as the only member of the genus Inachis. It should not be confused or classified with the "American peacocks" in the genus Anartia; these are not close relatives of the Eurasian species. The peacock butterfly is resident in much of its range, often wintering in buildings or trees. It therefore often appears quite early in spring. The peacock butterfly has figured in research in which the role of eyespots as an anti-predator mechanism has been investigated. The peacock is expanding its range and is not known to be threatened.
The small tortoiseshell is a colourful Eurasian butterfly in the family Nymphalidae. Adults feed on nectar and may hibernate over winter; in warmer climates they may have two broods in a season. While the dorsal surface of the wings is vividly marked, the ventral surface is drab, providing camouflage. Eggs are laid on the common nettle, on which the larvae feed.
Nymphalini is a tribe of nymphalid brush-footed butterflies. Common names include admirals, anglewings, commas, and tortoiseshells, but none of these is specific to one particular genus.
Nymphalis, commonly known as the tortoiseshells or anglewing butterflies, is a genus of brush-footed butterflies. The genera Aglais, Inachis, Polygonia and Kaniska, were sometimes included as subgenera of Nymphalis but they may instead be treated as distinct genera. See also anglewing butterflies. For other butterflies named tortoiseshells, see the genus Aglais.
Aglais milberti, the fire-rim tortoiseshell or Milbert's tortoiseshell, is considered the only species of the proposed Aglais genus that occurs in North America.
Aglais ladakensis is a species of nymphalid butterfly found in Asia.
Aglais rizana, the mountain tortoiseshell, is a species of nymphalid butterfly found in Asia.
