I occasionally see these monster bugs at night during the summer. I managed to get daytime photos of an injured one. It was on my patio in Twentynine Palms, CA. I’ve seen bigger ones before. I used a metric scal and also a tape measure in inches. Can you please tell me what it is? Thank you.

Palo Verde Root Borer

Hi Gail,
This impressive beetle is a Ponderous Borer,
Trichocnemis spiculatus.  According to BugGuide:  “Grubs are found chiefly in ponderosa pine and Douglas fir”

Correction:  Palo Verde Root Borer
Seems we were hasty in our identification and when that happens, we sometimes make mistakes.  Thanks to a comment from a reader, we have made a correction.  See BugGuide for confirmation.

Hi,
I observed this bug this afternoon. It can fly (pretty spastically) or walk and live in a hole in the ground into which it seemed hellbent on bringing scraps of wood bark and other stuff. It even picked up a big piece of dried mud to seal the entrance of it burrow. It is probably 2 inches in length.

Steel Blue Cricket Hunter

Dear AKizme,
This sure looks to us like a Purplish Blue Cricket Hunter,
Chlorion cyaneum.  The common name would appear to be a bit misleading, because instead of crickets, BugGuide indicates:  “Nests are provisioned with cockroaches.”

Correction Courtesy of Eric Eaton
Should be Chlorion aerarium, but without knowing what kind of creature it was hunting, I can’t be absolutely certain.  Chlorion aerarium is common and preys on crickets.  Chlorion cyaneum is less common and preys on cockroaches.
