NOTE: As of 2014, the California Beetle Project page is no longer updated.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:

  1. 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/

  2. A literature- (and available specimen-)based checklist.
    3. of the Coleoptera of California, which is being revised and re-compiled by Dr. Gimmel, and, as of January 2017, is about 85% complete.

What it looks like: 4.2-5.5 mm in length. Its body is dark reddish-brown, somewhat flattened, and very elongated. The pronotum is grooved, and the elytra have very fine striae, or shallow punctures, arranged in rows that run their length. The antennae are clubbed at the end.

Where you'll find it: This species is widespread throughout western North America. It can be found from southern California to British Columbia and as far east as South Dakota.

Natural History: These beetles live under dead pine bark, where they prey on other wood-feeding beetles. They are particularly abundant on ponderosa pines. They are the only common western species of the genus Aulonium.
