peacock butterfly

peacock butterfly (Aglais io; Syn.: Inachis io, Nymphalis io)


The European Peacock (Aglais io),more commonly known simply as the Peacock butterfly, is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. Formerly classified as the only member of the genus Inachis (the name is derived from Greek mythology, meaning Io, the daughter of Inachus). 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 where the role of eye-spots as an anti-predator mechanism has been investigated.[4] The Peacock is expanding its range[5][1] and is not known to be threatened. The butterfly has a wingspan of 50 to 55 mm. The base-colour of the wings is a rusty red, and at each wingtip it bears a distinctive, black, blue and yellow eyespot. The underside is a cryptically coloured dark-brown or black.


The Peacock can be found in woods, fields, meadows, pastures, parks, and gardens, and from lowlands up to 2,500 metres (8,200 ft) elevation. It is a relatively common butterfly seen in many European parks and gardens. The Peacock male exhibits territorial behaviour, in many cases territories being selected en route of the females to oviposition sites


A butterfly has only 2 gramms of weight ;-) !
