The European peacock or simply the peacock butterfly (Aglais io, formerly Inachis io) is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. The peacock butterfly is resident in much of its range, often wintering in buildings or trees. It therefore often appears quite early in spring.
