Yes, Zilla, I do know the name of the butterfly. It is a Painted Lady, Vanessa cardui.
Of course, I didn't know when you asked me, but I have garnered quite a collection of online resources in my 12 years as mother of children who ask nothing but questions. Look at this wonderful UGA site. I needed other pictures to make the identification, but I just happened to have them, since Princess was trying to capture her image for the Neshoba County Fair Photography Competition and took about 50 images of that butterfly and zinnia. She wasn't pleased with any of them. See why I need so many extra external hard drives.
Once you finish identifying butterflies, you can also identify birds, frogs, lizards, turtles, insects, plants, and fungi. I would have to say that it is a most useful site for my questioning, nature children.
