HI. We saw this yesterday. They are mostly black but there are a few with red markings underneath. I couldn’t tell if they were preying on the red marked ones or if they were all feeding on the same thing.
I don’t often see such large groups of beetles, except on my cucumber plants!
Based on this image we located on BugGuide, we believe this is an aggregation of White Margined Burrowing Bugs, Sehirus cinctus, but interestingly, there are only images of individuals on BugGuide.
