Female Pseudomasaris on Phacelia Mutabilis - Pseudomasaris zonalis - Female
SFSU Sierra Nevada Field Campus, just east of Bassetts, Sierra County, California, USA
July 13, 2011
Here she's collecting pollen from the Phacelia mutabilis flowers. Pollen is regurgitated with nectar to form a provisioning mass for the eggs she'll lay in the nest she has constructed.

Nice series of P. zonalis, Aaron!
They're so much fun to observe, and I wish I could have been up there.
In this female, the yellow of the upper orbits is not produced toward the ocelli as in P. coquilletti. The propodeal spines are small as we'd expect in zonalis; they're longer in both edwardsii and coquilletti. Also, your wasp lacks the anterior prominence / bump seen on the mid-tibia of P. edwardsii females.
I'm glad we now have zonalis images on BG from northern California, and nice that you have images of both pollen gathering and taking of nectar!
