Comment from alisonnetta on this observation.

Myopa usually has some ruddy tinge to it, and has a very deep face. Thecophora, the other Myopinae genus with a double-jointed proboscis, always has a blackish thorax, and no hint of red. Zodion has a gray-and-black striped thorax, and a long, single-jointed proboscis that points forward at rest.

This should be M. vicaria, as it seems to have open posterior cells, and only the wing cross-veins are heavily blotched. Also, the long, dark hair fits. There are other Myopa with patterned wings, but they don't occur in Idaho.
