Male Tile Horned Prionus

Dear Max,
The male Tile Horned Prionus, which is pictured on BugGuide,
Prionus imbricornis, is one impressive beetle.  According to BugGuide:  “larvae feed in living roots, primarily oak and chestnut, but also grape, pear, and corn.”  BugGuide also includes this reader observation:  “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.”
