Moved
Moved from Pseudomasaris.
You should also find zonalis in your area, probably at altitudes above 6000 ft., also edwardsii. Both species visit Phacelia for pollen, edwardsii also Eriodictyon.
P. vespoides utilizes Penstemon spp. as a pollen resource; where did you find this female?
At least two spp. of Hydrophyllum occur in Lassen county: H. capitatum var. alpinum, H. occidentale. Pseudomasaris mcneilli, is a pollen wasp known to use Hydrophyllum.

Thank You Hartmut!
... for your help with this wasp. This wasp was found here in Westwood. There is a fair amount of purple penstemon plants growing in the and fields around here, and That may be where I caught this wasp. There is also at least one species of Phacelia that grows in the fields and woods around here; so I will keep an eye open for species zonalis and edwardsii. Hydrophyllum capitatum also grows in the local woods, but does not seem to be real common.
