The European Peacock (Nymphalis io), more commonly known simply as the Peacock butterfly, is a well-known colourful butterfly, found in temperate Europe and Asia. It is the only member of the subgenus Inachis, which is included in Nymphalis genus, (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.
