Black/beige-gray cactus longhorn - Coenopoeus palmeri

Black/beige-gray cactus longhorn - Coenopoeus palmeri
Organ Mountains foothills, Dona Ana County, New Mexico, USA
August 9, 2006
Size: 17.5 mm
This beetle showed no interest in my UV lights. I found it on a headlamp stroll about 15 yards away from my lights on the dark side of a cholla cactus where it was busy munching away. It clung to the cactus with a fierce tenacity and it took me several tries and cactus needle pricks in my fingers to dislodge it.

They did not have this species in the NMSU collection.

Longhorns were not as prevalent as I expected (or maybe hoped), but a few that I'll be posting were quite exceptional.

A different kind of Cactus Longhorn!
This is indeed a Cactus Longhorn, but of an entirely different genus. This is the Cactus Longhorn Coenopaeus palmeri. It can be distinguished from C. niger by the very fine brown pubescence, or hair, on the upper surface of its body.

Thank you, Michael.
I suspected a different genus due to substantial morphological differences but had no idea which one. I'm glad you found bugguide. We can certainly use your expertise.
