I think Dasysyrphus creper, using the new Locke and Skevington Key (Zootaxa 3660, 2013). It could also be D. lotus, but I think it's D. creper.

The maculae of tergites 3-4 do not reach the edge of the abdomen, and are quite curved (unlike D. richardi, and more curved than D. lotus), meeting in the middle and broadly touching the anterior edge of the tergite. D. lotus has somewhat similar markings, but they're less strongly curved, though you are within their range as well.

I think you're correct, Kelsey -

Just looked at that paper. Its a beautiful fly and I hope to see it again coming year and get a specimen.
Was about to move it to species, but Charlie beat me to it.
By the way, I noticed you're interested in Mimulus, a fascinating complex with a number of new species on the horizon.

Oh goodness, don't get me sta

Oh goodness, don't get me started on Mimulus guttatus :^)

(for some reason, now that I'm discussing my study system, I feel like I should be less lazy regarding italics... wonder why)

Fortunately the two species I work on are fairly well defined, although one has two geographical races that are probably actually different species. And, fortunately, various folks have done all the bidirectional crosses and natural history research and so on, so we know a lot about my section of 7 (8?) species.

But elsewhere in the genus... guttatus is interesting, aurantiacus is another interesting complex (I saw a nice talk on the phylogeny of that species complex this summer)... wow. Species diversity is amazing!

Excellent - glad to have the second opinion! It is definitely a lovely fly - and those are some great pictures.

Dasysyrphus

With the comma shaped spots and the dense hairs on the eyes, it is clearly a female of the genus Dasysyrphus. The species are a bit difficult to tell.

Thank you, Martin,

so there are Dasysyrphus out here in CA.
