Field notes and information

ARIZONA April 2015: Just as in Europe, the Colias are a difficult group to differentiate. In Arizona it seems there are two very similar species - I think I only found this one. But I'd be happy to hear from any experts if I've got it wrong.

Uncommon but widespread, we found a few individuals around Phoenix and SE AZ.
