Moved from Small-headed Flies.

From the uniformly narrow white abdominal bands and wing venation this is evidently Ogcodes, but I'm not sure of the species.

The black legs would seem to exclude O. borealis, and the range map for that species doesn't extend into southern Calfornia.

The black legs together with the pale post-alar callosities (at posterior corners of the thoracic dorsum) are consistent with O. pallidipennis...and I think(?) western females of that species can be expected to have black abdominal dorsum (excluding the narrow white bands)...but I'm not certain. And O. melampus is also a possibility, though I don't know it it can have the pale post-alar callosities seen here.

Hopefully Dennis Haines or someone else can help with species here and will comment...but the keys are centered on males, and females are thus likely harder to ID.

Documentation
I can try to get more images of these this summer as I live right next to where it was photographed.

Thanks for the education.
