It's a bug. :-) There's tons of such critters around here and I know just a couple of them. BTW, you never said whether it's hard-shelled or soft-winged. It's difficult to tell from the photo. I'd guess soft winged. BTW2, this summer I saw a rhino-bug. with just one horn on the top of the snout. It was something like three inches long and incredibly strong for its size. When I returned with my camera, it was gone. And I hadn't had anything to cover it and keep it in place. :-(
