Hello!! I have never seen this bug in Pennsylvania before! It was a humid summer evening, and I noticed it on my outside screen. Nearly 2″ long it’s body alone, it made a squeaky kind of noise when it walked away from us on the ground. Took this picture as it was on the ground. What is this bug??

Brown Prionid

Dear Debbie,
This impressive beetle is a Brown Prionid.  The squeaking you heard is called stridulation.  The beetle makes the sound by rubbing parts of its body together.
