Updated: I'm especially curious about these! In Bindweed. Please note the different-colored eyes and different body shape. They were "friendly" towards each other, sharing the flower, and did not otherwise interact. This Observation is for the DARK-EYED bee at the top of the first photo. The Observation for the BLUE-EYED bee is here: https://www.inaturalist.org/observations/77602608
Have been seeing a few of these on the various salvias in our yard.
On Eriogonum parvifolium
What looks like a black-tailed bumble bee buzzing on ornamental azalea
Pretty big, atleast an inch. I thought it might be a queen
