Hi! I am in the panhandle of Florida, right on the coast. Today I was very surprised to find what looked like the Mother of All Cockroaches outside of my office. The bug was about 3.5”-4” long and very wide- about 1”-1.25”. He had very thick legs and had wings. He looked very much like a cockroach except for his slightly curled, droopy antennae. I think he was injured (he was in the same spot most of the day) so I didn’t get to see how he moved. Also, sorry for not getting anything in the picture for scale – I was too terrified!
I hope you can help me. Thanks!

Hi Natalie,
We wish you had a better view of the head and mandibles on this impressive beetle.  This is a Longhorned Borer Beetle in the subfamily Prioninae, but we cannot be certain of the species.  Based on the antennae and the thoracic region, it most closely resembles the Hardwood Stump Borer,
Mallodon dasystomus, which you can view on BugGuide.

Thank you for responding! Very interesting!
