Like the Peridot Sweat Bee of my previous obs (https://www.inaturalist.org/observations/58638198), the Blood Bee was feeding via (possibly already made) slits in the tubular flowers of the California Fuchsia. (Pic 4: possibly an Assassin Bug, discovered in the photo.)

I think this could be a Genus Andrena bee feeding on California Brittlebush. The coloring of the bee reminded me on a Cherry Plum Mining Bee I saw a few weeks ago, https://www.inaturalist.org/observations/38982903.

This bee was hovering over the nests of Bindweed Turret Bees (https://www.inaturalist.org/observations/49582640), and also crawled into a tunnel-shaped nest entrance. Was this a predator/parasite, or was this bee nesting in the same spot?

Nest site, about 20 x 7 meters, with several hundred bees buzzing about. The bees are a bit smaller and much hairier than the Diadasia bituberculata we saw about a month ago. It’s a disturbed chaparral area, part of a fire road. Flowering plants include a few Common Sunflowers, Telegraphweed that’s just budding, and Shortpod Mustard.

Description

Going to need to get expert confirmation on this ID but the Type Locality and host plant are correct for this ID. Feeding at patch of Sulphur Buckwheat on East ridge of Tehachapi Mountain. Although there was a lot of Wright’s Buckwheat on the ridge too, it was not blooming which implies that this butterfly’s host is E. Umbellatum since Euphilotes only emerge when their host plant is in bloom. Elevation 7500ft +. Sunny day in the high 70’s F.
