This was on my front door lastnight, cant find a discription of any like it online. It was app. three inches long.
This is a Root Borer in the genus Prionus. It is a male Tile Horned Prionus, Prionus imbricornis. BugGuide provides this identification information: “Huge longhorn, dark brown and shining. Antennae have 18-20 overlapping segments (male): Female has 16-18 serrated segments. Other eastern Prionus have 12-13 antennal segments.” BugGuide also provides this information which may explain this Tile Horned Prionus’s appearance on your porch if the light was left on: “On mid-summer nights, these hit lighted windows so hard at my house in Durham, North Carolina, that I fear the glass will break. Seems that mostly males come to lights.”
