California Prionus
We found this at night in El Cajon CA. It was about 2.5 inches minus the antennae. Thanks to your site for helping us identify it as a California Prionus. In the jar it made a squeaking sound. We let it go the next day. The pictures are big but they came out pretty nice. (We named it Cruliette. ) Thanks,
Kylie, David & Emily
