Found this imposing looking bug on my kitchen screen door. Didn’t seem aggressive, but those pincers look like they hurt! Should I move and concede the territory?
In our opinion, you should not move and concede the territory because of your encounter with this male Reddish Brown Stag Beetle, Lucanus capreolus. Females have smaller mandibles. Stag Beetles will use their mandibles to defend themselves, but as you observed, Stag Beetles are not aggressive, nor are they dangerous. They are attracted to lights, which probably explains its presence on the screen door.
