In the late afternoon, I found a number of these Eulonchus resting within corollas of Penstemon heterophyllus. I gently nudged a few of them out a bit so I could photograph them. They made an interesting, fairly loud, high-pitch buzz...clearly a sign of irritation, and it seemed to be an attempt to mimic a bee in order to deter me.

The females in this group had pure metallic-green abdomens, whereas the males had more red-to-golden tinged abdomens. Note the prominent ocellar tubercle.

This was from the same group as in this other post.

Photos from this population are identified as E. tristis in Fig. 1I, pg. 109 of Borkent, Gullung, & Winterton(1)(2016). Apparently, the margins of the calypters are not dark enough to make this E. marginatus.
