I live in Glen Burnie, MD and saw this bug on my back porch. I am not sure what it is, so I thought I would ask you. So, what is it? He looks pretty scary. He was found at night. Thanks.
We are being besieged with images of Prionid Beetles in several genera from coast to coast. Your trophey male is one of the most spectacular, the Tile-Horned Prionus, Prionus imbricornis. You can see more on BugGuide. We especially love your head-on view of his magnificent antennae.
