@blaise It looks for all the world like a black beetle. https://bugguide.net/node/view/163374 Amara aulica pretty rare in NA but common all over europe. It can bite but they're not venomous.
@scottgal omg, it sure does! I didn't see anything similar in the local "pests of Kentucky" site. I sure hope it isn't the first sighting of a new invasive species.
