Although the adults don't eat much, the nymph's food does include aphids, so this is a plus in my book.

Found throughout the eastern US and Canada, the sexes are easily identified by the male's larger head and jaws.

Adults fly at night and are attracted to artificial lights, they hide by day in moist soil and wet rotting logs.

I have not been able to raise this one from egg to adulthood though others have done so. The females are harder to find and the males do not run and hide in daylight as most beetles do after flying about at night

This guy landed on me near a corn field on 7-12-08. There were no trees near by but it was a windy day.

At about 10:30 PM I heard a loud noise outside my window. It sounded like a huge bug flapping its wings against the window. Me, while thinking it was a June Bug, opened the blinds to find a huge, brown beetle with large pincers. It was around 3 or 3 1/2 inches long. I identified it as either the Reddish-Brown Stag Beetle or the Giant Stag Beetle, as the Giant Stag Beetle is listed to be "2 to 3 inches long", and the beetle was definately at least three inches long.

Just found one of these on our front porch about an hour after dark. This is the first time we've seen one, it was about 2 inches long.
