Moved from Chilocorinae.

I finally got it! The sparse, very short pubescence indicates that this is B. histrio. None of the other species with similar patterns are pubescent.

This may be the longest it's taken me to ID a lady beetle...it's been nagging me for four years. Champagne, anyone?

Brumoides histrio is similar and in your range, and a much better bet than my extralimital suggestion before, I think:


There's also a similar subspecies of another Brumoides species that we don't have illustrated on BugGuide, B. septentrionis hogei, and it's also in your area.

So I still don't know what it is but there are a few more possibilities that do live in the right place! I'm going to ask around and see if I can get this narrowed down any better.

Moved from Lady Beetles.

My initial impression from the thumbnails was Hyperaspis but seeing the dark head, black eyes, and short stubby antennae has changed my mind. Those are all characteristic of Chilocorinae, and of those, it is a PERFECT match for Exochomus californicus except for the location. It hasn't been recorded in Utah, that I know of; the range is supposed to be limited to California and western Nevada. However, one of them was found in Minnesota once, so clearly they occasionally are outside that main range.

I don't know what it is if it isn't E. californicus. The only other beetles like this are in Hyperaspis and they have blue eyes and much longer, thread-like antennae.

Let's put it in Chilocorinae for now to get it off the main LB page, and I'll ask around about any known range expansions or other extralimital findings.
