Centris (Paracentris) sensu lato - Centris hoffmanseggiae -
Borrego Springs, San Diego County, California, USA May 4, 2008 Size: BL up to 18 mm?
This large bee, which appears to be a Centris female, was visiting a large Mexican Palo Verde in full bloom that was swarming with many bees and wasps on Henderson Canyon Road in Borrego Springs. It has a white clypeus. Could this be the female Centris cockerelli?
