Queen Butterfly at Agua Caliente

Out in the desert in late April I noted many orange butterflies with black lines in the wing. I'm sure these veins have some special name, but I haven't really studied butterflies. I do, though, photograph them when I get the chance.

I was told they were Viceroy butterflies, and I knew that Viceroy and Monarch butterflies were very similar. However, later I learned that they were Queen Butterflies (Danaus gilippus)--a name I'd never heard before. Sure enough, the many white spots amid wing identify this species.
