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??
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.
