A large beetle flew into my screened-in back porch, and I’m having trouble identifying it. It is 2” (50mm) long, and 5/8” across at the top of the wings. I have seen some photos that are similar, but not an exact match. Any idea of what this beetle is? I have a few more pictures if you need them…

Hi Joey,
This positively magnificent beetle is one of the Prionid Longhorn Borers, and more specifically, it is
Mallodon dasystomus, the Hardwood Stump Borer.  Adults are attracted to lights according to BugGuide.
