Robber Fly on Coffeeberry leaf - Stenopogon californiae?

Here is an impressive Robber Fly (family Asilidae, Diptera) on a leaf of California Coffeeberry (Frangula californica aka Rhamnus californica) in the Rhamnaceae plant family. This one might be species Stenopogon californiae. It's close to an inch long and has impressive whiskers! These flies are predators that catch their prey on the wing between their bristly front legs, like the dragonflies they resemble. They don't visit flowers, so there's no easy way to find them. I've seen this kind before on the same plant, see this photo. It's not quite Friday by local time, but it is by Flickr/GMT/UTC time, so HFDF! (San Marcos Pass, 19 July 2018)

Today was less cloudy than yesterday, but there was still a haze in the air. There was a steady breeze from the south again that made it difficult to get sharp photos. It was warm but not hot, in the mid-80s. There's still some humidity in the air, but no threat of storms.
