Butterflies: Pearl Crescent

Photo of Pearl Crescent

The Pearl Crescent* (Phyciodes tharos) is a common New England butterfly, present in all but northern Maine. The similar Northern Crescent (P. cocyta) has a more northern distribution and was formerly considered the same species. I photographed this individual in Wells, ME.

*I've since learned that it is quite difficult to tell Pearl Crescents and Northern Crescents apart. Given the fact that both species are found in Maine, and I am not a butterfly expert, it is possible that my photos are of a Northern.

Butterflies: American Copper and Pearl Crescent

Last week, I found these butterflies (American Copper, above, and Pearl Crescent*, below) nectaring on Lance-leaved American-aster (Symphyotrichum lanceolatum).  As the white season approaches, fewer species of butterflies remain active, but some are still around for the observant naturalist to notice.

*I've since learned that it is quite difficult to tell Pearl Crescents and Northern Crescents apart. So, it is possible that my identification is incorrect. If I'd taken this photo in Massachusetts, where only Pearls are present, I'd feel more confident about my ID, but here in Maine, both species are possible.
