Comma Butterfly?
Dear Bugman:
I’ve searched your site high and low, and (unless I missed it) I can’t find this critter anywhere. It appears to be a Comma Butterfly of some type, but I can’t find any in your pics that have the white spots on wings. Can you help me ID this fellow? Thanks in advance!

Hi Robin,
That was a good guess. This is a Compton Tortoiseshell, Nymphalis vau-album, a near relative of the Comma and other butterflies in the genus Polygonia. The Compton Tortoiseshell is in the same genus as the Mourning Cloak. The caterpillars feed on birch and willow. Thanks so much for adding a new species to our site.
