The Pandora Sphinx

At work the other day I found this moth (or one just like it) on the upper level of our stadium. It was dead, but it couldn't have been for long. When I first glanced down, I thought it was a G.I. Joe hang glider. After doing a Google search, I discovered it is called a Pandora Sphinx. I think the name is pretty cool, too. This individual moth was about 3-1/2 " across.
