SBMNH Entomology - The California Beetle Project

NOTE: As of 2014, the California Beetle Project page is no longer updated. The original database and list of California beetles in the menu on the left will remain for the time being, but the information contained within is not necessarily current. SBMNH Entomology Curator Matthew L. Gimmel has divided up the function of the original database into two conceptual halves:

The SBMNH Entomology specimen-level database, including all SBMNH beetle specimens included in the CBP database, which is now available (and ever-growing) through the ecdysis portal at https://serv.biokic.asu.edu/ecdysis/
A literature- (and available specimen-)based checklist.

What it looks like: 4-5mm in length. Its body is light to dark reddish brown, flattened, and with rounded elytra. The pronotum is smooth, while the elytra have distinct rows of punctured striae. Its antennae are elongate, and gradually widened toward the tips.

Where you'll find it: From higher elevations of southern California (including the San Jacinto and San Bernardino ranges) north through the Sierra Nevada into Oregon.

Natural History: This species is probably a general scavenger on decaying organic material. It is most often found under and among debris in moist places, especially along montane streams. They are primarily active at night, and may then be found out running around stream edges.
