Butterflies: Atlantis Fritillary

When I hiked up East Royce Mountain last month, I reached the summit to find an Atlantis Fritillary (Speyeria atlantis) nectaring on the white flowers of Labrador-tea. I've found the various species of fritillaries to be tricky to tell apart, but thanks to the BugGuide, I now know that eye color can be a useful field mark.

Atlantis Fritillaries have blue-gray eyes, unlike the brown or red eyes of the other New England fritillaries. Had I known at the time, I would have tried for a more artistic eye-shot, like the one by Mark Olivier available here.
