I don't know what kind of beetle this is, but it obviously got into a tangle with a spider web and while it is free, it can no longer fly. That bit of wing cover was stuck that way. It just kept crawling around and around the birdbath. Probably made a nice snack for a bird eventually. Shot w/the OM 90mm f2 macro at probably f2.8 or 4.
