Fly in Yarrow - Musca autumnalis - male

Fly in Yarrow - Musca autumnalis - Male
Big Basin Redwoods State Park, Rancho del Oso, .8 mile loop, Santa Cruz County, California, USA
July 23, 2011
One of a couple of these seemingly similar (to me) darker flies I find in Yarrow or Cow Parsnip, but not the Hemlocks or Oleanthe, who seem to have their own following, mostly syrphids, and I note a lack of syrphids in the Yarrow/Parsnip

Bristles
Seeing the bristles on top of the thorax and under the base of the wing (small bristles behind a prominent row of bristles; may be present or absent depending on family) would help. Sarcophagidae and Tachinidae usually have more bristles in some places than Muscidae.
