Beautiful, isn't it? I don't think the picture does it justice. It kind of looks like it has a tile mosaic on it's back. I thought it was related to a firefly, thus a beetle, but I was way off. It is an Alianthus-Webworm-Moth. And, interestingly enough, Indiana isn't listed as a state it is found in. Ohio is, though, and that is just a stone's throw away. Bugs are cool in the country! If you find one and you don't know what it is, insectindentification.org has a handy-dandy database you can search by color and state.
