Butterflies

I guess it's not too early for butterflies. There were quite a few of them up at City Creek yesterday. Looked like they were all the same species, too. I've posted some pictures below the fold. I think they're brushfoots again, maybe hoary commas or green commas (which are closely related to the Tortoiseshells). Based on the descriptions, they're more likely to be green commas. No clue what's green, unless maybe they have a green chrysalis? Ah, this might be why they're out so early: "Adults hibernate and mate the following spring."
