Obvious Marking, Pt. 2 - _TNY_0020

The comma butterfly (Polygonia c-album) is named that way because of the white mark on the underside of the wings. It obviously can't be seen from this angle of a specimen I found at Åva-Stensjödal in Tyresta National Park, but if you check out part 1, the reason for the name should be very clear: www.flickr.com/photos/tinyturtle/48323209396/
