This fly is "basking" on the petal of a California Poppy and this is a typical spot to find them. Location: Santa Barbara, California, USA. Length: 5mm. Empodia absent. R4+5 not forked. Frontal suture present. Outer suture on 2nd antennal segment (corrected). With complete transverse suture (corrected). Oral vibrissae present. Costa spinose. Postverticals converging. No specimen collected. Family? Genus? Species??

[To remove any confusion I have corrected my original post based on a new photograph.]

A rather typical male Anthomyiid I think.

Anthomyiid? . . . but no suture on second antennal segment and no complete transverse suture.

I think I can see the suture on the second antennal segment (right antenna), though. I agree with Xespok about the Anthomyiidae.

Well, I'd still put my money on Anthomyiidae. But better wait Andrzej than, he is the Heleomyzid expert here. There are also Heleomyzids with this jizz as well.

"I'd still put my money on Anthomyiidae..."
I eat my hat on Anthomyiidae!

I am absolutely certain it is not Heleomyzidae. If it is not Anthomyiidae, then another calyptrate, but I think that will not be the case.

No one eat their hat yet! A different photo I just took shows a second antennal suture and the weakest transverse suture I have ever seen. Anthomyiid it is . . . now, which species? ;)

Nice photo.
But I wish I have answer in cases of collected Palearctic specimens of this kind...
