HELP!

Help! We need someone to tell us what type of butterfly is pictured. Isn't it beautiful?!
The wings have the gorgeous spot pattern to scare away predators and a soft pink color that stripes up the back of the wings. So pretty.
The body on this particular butterfly is really big. I don't know if it is supposed to be that way or if the butterfly is bloated (too many leaves - I don't know) :).
Actually, we're wondering if it is sick or what. It is just hanging out in the street in front of our house. We moved it with a leaf as far as we could. We tried to get it to the grass, but the farthest we could move it was the curb - just beyond the grass.
At first we thought the butterfly was dead, but then when we tried to move her, she opened her wings. Most of the time she sits with her wings pulled closed above her fat little body.
So, please. Help us ID this beautiful butterfly. We're so curious. We looked on-line, but couldn't find anything to match.
