Question Mark, Polygonia interrogationis <LEP127>

There are two seasonal forms of the eastern anglewing. In summer forms the hindwings are almost completely black. In the autumn form both the fore- and hindwings are bright reddish orange with heavy brown markings. Both forms have a lilac-purple border, narrower on the black-spotted summer butterflies. The autumn generation survives the winter as adults, which in turn produce the summer form generation.
