Plasterer Bees

Back to take photos of the ground-nesting bees I saw yesterday. Identified as plasterer bees (Colletidae Colletes), named for their habit of lining their nests with a secretion that dries into a thin clear sheet. When a male found a female, they were pounced on by what I assumed were other males attempting to dislodge the original male so they could mate with the female.
