My friend saw this bug crawling in the grass around her home in central PA. She’s never seen this before and neither have I.

Rove Beetle

Dear Denise,
This is a Rove Beetle, but we are uncertain of the species.  We love the aggression of Rove Beetles, but except for the Creechies, Rove Beetles are harmless and do not sting.  Our favorite Rove Beetle is probably the Devil’s Coach Horse.  Your Rove Beetle somewhat resembles
 Platydracus maculosus which is pictured on BugGuide.

Thank you very much.  I’m glad it’s not the Creechie species!  One question though: The thorax on the bug she saw was not smooth and seemed to have a blackish/blue something on it.  Does this beetle molt?   Or perhaps it was injured and the exoskeleton is ripped partly away?

Adult beetles do not molt.  Perhaps you are seeing the flight wings which are hidden beneath the short elytra.
