Darkling and Ironclad BeetlesIdentification request
Location: Moapa, Nevada
January 28, 2012 8:43 pm
I’m after an identification confirmation or other options. Images of Paracotalpa deserta are the hardest to find of the four species. That said, this matches Field Guide to Beetles of California description for a ”Little Bear” scarab beetle with January thru March time of appearance, creosote-bursage desert habitat, and general description as ”black”. These were 9mm long.

Darkling Beetle: Edrotes ventricosus
Dear Bruce,
The antennae on these beetles are wrong for a Scarab. We believe we have correctly identified it as a Darkling Beetle, Edrotes ventricosus, by matching to photos posted to BugGuide. The species has been reported in California and Nevada.

THANK YOU for the identification AND especially for the antennae comment.
The latter sent me back to field guides and websites to look at what I
missed and OF COURSE the antennae are not correct for a scarab beetle and
are correct for the Tenebrionidae. I’m just starting to work in the
insects and my learing curve is nearly vertical.
Bruce
You are most welcome Bruce. It always helps to have more than one set of eyes when doing unusual or difficult identifications.
