Travelin’ Show

This guy is a bit tattered around the edges but is still a very handsome specimen of whatever kind of butterfly he is.  Since I’ve never seen his like before around here, I’m wondering if he’s migrating from/to somewhere.

**UPDATE** Some kind person on Flickr identified this as a Mourning Cloak (Nymphalis antiopa). It must indeed be migrating as it normally summers in Montana. We are quite a ways east of it’s normal path!
