I'm 99% sure this is
P. edwardsii
, though I can't see all of the diagnostic characters. The propodeal spine looks right, so do the yellow markings which are pretty much constant in extent in this sp.

P. cicutaria var. hispida
, or
Phacelia ramosissima
, both of which occur at Laguna. Based on what I know about the size of those flowers & their stamens I'd guess at a length of 12mm to at most 14mm for this pollen wasp.
Oh, try to find some males next spring. Though they're not as numerous as the females, you can detect them by their busy flight pattern & long, spectacularly clubbed antennae:

OK. Short antenna = female. How broad is that? All wasps? All hymenopterans? All Vespids?

Not always.
The distinction is just incredibly dramatic in this genus! Moved to genus page. I have a key back home in Tucson, so if no one makes a species determination by January, let me know and I'll run your images through it.
