One of my favorite photos. Took this in Aug. 2006 just after a record rain and flood in the desert off the Franklin Mountains in El Paso, TX. The abdomen of what appears to be a type of ant was roughly 1/2” long.
I’ve always wondered if the heavy and unusual amount of rain affected this bug’s normal appearance.

Desert Spider Beetle

Hi Christoper,
This is a Desert Spider Beetle in the genus
Cysteodemus.  Some members of this genus are known as Inflated Beetles because of the air filled abdomen.  Your beetle is the Black Bladder-Bodied Meloid, Cysteodemus wislizeni, which you may read about on BugGuide.  Rain frequently triggers activity in desert dwelling insects.
