E. anicia is a reasonable call
I just commented a little while ago with one of the caterpillar photos that it was too bad there wasn't an adult photo. Ask and ye shall receive. :0)

Anyway, I am very tempted to buck tradition and put this under E. anicia, because it sure looks like E. anicia to me too. However, all the listings call the orange Sierran populations E. chalcedona; this based on the male genitalia. This orange butterfly and more typical dark E. chalcedona of other subspecies both fly in the Sierra Nevada, and it will take some convincing for me to believe they are the same species. Regardless, this is the orange Sierran representative of the group, greographically replacing [E. anicia] ssp. wheeleri, which occurs further east in the Great Basin.

Close
That's close, but I'm leaning more towards Euphydryas anicia.
