Subject: Iridescent green/blue beetle in New Mexico?
Location: Albuquerque, New Mexico

We saw these beetles in our yard recently. The only other one we have seen was found dead, two or three years ago. One was a hole dug by our dogs, gripping the vertical surface. It’s near what looks like a burrow. The other was seen a few days later, in the same general area, but out in the open. The beetles are iridescent green or blue, depending on the lighting. They are quite bulbous. These two were different sizes, but between 1/2” and 3/4” long. I haven’t been able to identify anything similar. Please help!
We are in Albuquerque, New Mexico, on a mesa of volcanic rock and find sand. We don’t have a lot of vegetation around us, either.
Thanks for your assistance.

I kept searching and finally found it!  It’s clearly a Desert Spider Beetle (Cysteodemus wislizeni) according to pictures on your site.
Thanks for your great resource!
