The California Floristic Province is one of the world's great biodiversity hotspots. Ten thousand or more species of beetle call California home. Some are considered pests, but these are far outweighed by the countless species helping to keep our valuable ecosystems going. This project and website are dedicated to increasing appreciation and providing information on these fascinating and beautiful insects.

The links to the left lead to taxonomic checklists, a comprehensive, queryable distributional database, descriptions of ongoing fieldwork, a gallery of images of California beetles, ecological information for many of our species, and detailed information on several beetles considered endangered or threatened in California.

Specific information on the project can also be found, including the people involved in the project, and some of our field, laboratory, and informatics protocols. There are many opportunities for you to become involved in the project, by helping to inventory beetles in your area, or by providing financial support.

We are grateful for your interest in California beetles.
