Poecilanthrax californicus is a Western US species.

progressive bee fly
This little Bee Fly had a strange behavior, much like a Deer Fly.  It would fly by me and then it would land on
the sand or on a bush, then it would take off again for a short sput and then do it again.  I kept expecting
it to land on me and take a bite, like a deer fly would.  Once I realized it was a bee fly, I enjoyed taking a few
 photos. I understand that the female lands on the sand and dips to deposit eggs with her ovipositor. 
When the larvae hatch they eat immature insects.   © Carol Davis, 10-6-2009
