Pollen-Wasp on Phacelia ramosissima - Pseudomasaris coquilletti - female

Pollen-Wasp on Phacelia ramosissima - Pseudomasaris coquilletti - Female
Cedar Mountain, Alameda County, California, USA
May 19, 2012
Frontal view, showing interesting patterns on frons and clypeus. She was collecting pollen off the anthers, which is stored in a crop for provisioning larvae when she returns to her nest. (I believe the adults also feed on pollen, in addition to nectar, to fuel their activities.)
