Madrona Marsh Preserve, Torrance, Los Angeles County, California, USA

Found upside-down on the underside of a thick Willow branch.

Would this be a female Tachinid Fly ?
The stubby reddish antennae seem unusual ...

"Probably Muscidae"
That is what Norm Woodley wrote, in the remarks with the second image.

The Muscidae is not a very large family, at least in terms of number of nearctic genera.
A quick run through Cole's KEY yielded tribe Graphomyini.
Eliminating non-resembling genera Mesembrina & Hypodermodes, points to Graphomyia.
Graphomyia is arguably the best resembling genus, in overall habitus, among the Muscidae (on BugGuide).
I did not find any images sporing red antennae and/or a red bud, but this genus seems under-studied and perhaps under-represented.
In summary, could it be one of the nine (or more?) North-American Graphomyia species ?

I think I figured it out with the help of McAlpin's key.
How about Synthesiomyia nudiseta ?
