It looks tattered with much of the pigmented/prismatic scales rubbed off. Goatweed butterflies have a projecting tail on their hind wings. It's difficult to ascertain that with the butterfly in this condition.

Did it have a snout? If so I'm thinking Common Snout Butterfly. I'll post a picture.

Wish I could be of more help. Hopefully someone else has a better answer.

Thanks. It's not a Snout ;-)
Julia, Dryas julia was suggested on the Butterfly Forum.

If that's a Julia, it sure gives a bad impression of an otherwise breathtaking orange beauty.

And that julia won't get a second chance to make a good first impression.
