Western Banded Glowworm Beetle

Zarhipis integripennis

Description:

This is a male Western Banded Glowworm, in the genus Phengodes. Female phengodids are larviform, meaning they retain all the characteristics of the larval state, but have a fully-developed reproductive system, and compound eyes. They glow between the abdominal membranes. Larval and female phengodids feed exclusively on millipedes. The males are not luminescent. http://www.whatsthatbug.com/2005/06/17/m...

Along Chimney Rock Hiking path in Point Reyes, CA.

I think we can be confident of the superfamily Elateroidea. It looks similar to a soldier beetle (Family Cantharidae), but the antennae are all wrong. Judging from the shortness of the elytra and the branched antennae, I think we can safely say the family Phengodidae. I'm not 100% sure of the genus, but that's the closest I could find.
