Atlantis Fritillary

by Bryan on June 30th, 2010

Here’s an Atlantis Fritillary (Speyeria atlantis) nectaring on red clover. Our two other large Speyeria frits here in the East are Aphrodite Fritillary (S. aphrodite) and Great Spangled Fritillary (S. cybele). One reliable field mark is the ocean-blue eyes on Atlantis Fritillary; the two others have yellow eyes. This mark won’t work in the West, where the higher diversity of these large fritillary species is enough to make even the most dedicated lepidopterist content with (or relegated to) the wisdom that we cannot always know what’s flying before us.

By the way, DSA members looking for an updated species list can check DSA Update No. 4 again for the new version, which includes additions from Fryeburg and Jackman (although I haven’t listed species from those trips separately).
