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.
