Description

I see these small (like 5 mm) bluish beetles on flowers pretty frequently. This one was on a wallflower. Anyone know the family, at least?

It kind of looks like a few things (to me). Did you end up putting it on BugGuide? Do you have a pic from the top?

Nevermind, I think I figured it out...at least to subfamily.

Well, decent gestalt match, but my ignorance of the other options is pretty enormous. Do you have any of Arnett's American Beetles?

Yes, I have vol. 1. (they are pricey). I would love vol. II. My birthday is in a month. The other things I was thinking of were Bostrichidae, but the pronotum wasn't really right. I looked at a few other things from my BTJ textbook, but something was always off...either the antennae or the pronotum. Also, they like to hang out on flowers. Next time get a shot of it's palps and the ventral surface of the abdomen and the antennae and tarsal segments and I'll key it...
