in some classifications), an occasional visitor to my windows in mid-summer. The sound they make hitting the glass is pretty distinctive--this one came in about 9:00 p.m. and I placed it on a craft foam stage for a photo session. Light from a twin-head flash was diffused through a modified 1-gallon plastic jug. (I was pretty happy with this effect, though it could still be softer.) These are large beetles--length about 32 mm without the mandibles, 38 mm with them.
