Our 2023 fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. Your support is vital to the project. Please make a recurring or one-time donation to sustain this valuable source of information. Thank you!
Observation notes: Very active once temperatures warmed up.

Coordinator notes: Correct ID....usually the most common of the high altitude arctics, males on top of rocky ridges as you described. You can also find the White-veined Arctic on Independence Pass the time you were there....it likes lush tundra grass but this was not a very good year for lush grass at high altitude. My trip to Cottonwood Pass several days earlier than your date on the sighting found the high altitude drier than I have ever seen it before and very few butterflies....other than a few Melissa as you found.
