This bug was hiding in the sunroom INSIDE the house, cornered by the cat. The bug was aggressive and actually squeaked when confronted. Very large, two inch range. Sorry, the dead body is gone. But, we have a picture. Looking forward to any guesses. Thanks, Keith
This impressive beetle is a Brown Prionid, Orthosoma brunneum, and while we tend to get a few submissions of Brown Prionids each summer, we have had a significantly greater numer this summer. The larvae are wood borers and according to BugGuide: “Breeds in poles, roots(?) in contact with wet ground.” We suspect this individual was attracted to your house because of lights.
