Whatt is this bug???
We just found this large back beetle in our backyard in CT.
It has large pinchers & a tail/stinger/? that is usually recessed, but quickly comes out when aproached. It also sticks it’s rear end up, as if a defense as well.
Lastly, we found it over a 1/2” diameter hole, which it appeared to be protecting.

Hi Heather,
This is a female Broad-Necked Root Borer,
Prionus laticollis, and what you describe as a stinger is actually her harmless ovipositor that she uses to lay eggs.
