Nymphalis (Aglais) milberti, a close relative and presumably ecological
equivalent to urticae, has been very rare here in southwestern,
Saskatchewan Canada - it is usually the most common tortoiseshell. I
have only seen two all year. On the other hand, N. antiopa is quite
common, and I've seen N. vau-album around here for the first time.
