NOTE: As of 2014, the California Beetle Project page is no longer updated.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: 5-7 mm in length. Its body is elongate and dark reddish-brown. The elytra have striae (shallow punctures formed in rows) and there are distinct depressions right behind the shoulders. The head points directly downward.

Where you'll find it: They can be found in coastal regions from the Alaskan panhandle down to southern California.

Natural History: These beetles are active in the winter months and well-adapted for cold. They can be found near snow or in other moist environments, such as high mountain creeks. They're sometimes found under the bark of dead trees, including oak, Engelmann spruce, and western larch.
