The American Painted Lady (Vanessa virginiensis) is best identified when nectaring like this by the two large eyespots on the ventral hindwing. The very similar Painted Lady (Vanessa cardui) would have four smaller eyespots in the same place. This individual is tattered and torn, experiencing some wear and tear after being busy on the wing for probably only a couple weeks, or a few at most. Adult life spans are short for many of our butterflies, and they have a lot to get done in such a small window, which makes it all the more important to have plentiful, widespread and organic food sources.
