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.

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.
