Diadasia ochracea - male

Diadasia ochracea - Male
Theodore Payne Foundation garden, Sun Valley, Los Angeles County, California, USA
June 1, 2013
Size: 7 mm
For ID I used both Timberlake (1941) and Snelling (1994).
There's also an identified male specimen at Cal. State Northridge, from the Santa Monica Mountains.
Note the creamy-white clypeus, and base of mandibles (adjacent photo).
Though I was aware of some records for D. ochracea in southern California, I had not seen this bee in a natural setting.
After seeing a female in Sphaeralcea in my garden, but not finding any more for closer examination, I thought I'd look at the nearby Payne Foundation in the San Gabriel Mtns. foothills. Indeed, I found females packing pollen in flowers of Sphaeralcea ambigua. Went back yesterday to find the present male for some more photos.
