The European Peacock (Inachis io), more commonly known simply as the Peacock butterfly, is a colourful butterfly, found in Europe, temperate Asia as far east as Japan. It is 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 present 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. See also Anglewing butterflies.
