Several males grasped this recently emerged female but then let her go quickly. After several attempted matings like that, she flew away and was grabbed in mid-air by another male. I didn't see the outcome of that attempted mating.

Flicking eggs into nest entrance of a Pacific Dune-Digger bee (Habropoda miserabilis)
The basic sequence of this behavior is hover, flick eggs into nest entrance, back away, and repeat.
The first photo shows the approach. The second photo shows eggs + sand in mid-air on their way into the nest. The third photo shows the fly getting ready for another flick (and the wing pattern, which is helpful for identification).
The last photos show the wider view, with the bee fly being very difficult to detect because of its presumably cryptic coloration.

This observation is for the smallest individual, second from the left. The larger individuals have their own separate observation here.
These were just a few individuals out of many large flocks flying north.

Dead individual at a nesting site of Pacific Dune-Digger bees (Habropoda miserabilis). In the second photo, each little patch of clean sand indicates a bee nest, and the beetle is the black thing on one of the bee nests at the center-right.
