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. |
