bradmoonDescription
Simple arista--I looked for plumose structure with binoculars and through my camera and confirmed the arista were not plumose.
This fly was feeding in the same flower patch as one or more Hiatomyia and they do look a lot alike, especially males. I haven't seen many individuals or species of either genus and don't know if these differences apply broadly, but this individual has black flagellae (vs. orange in this Hiatomyia feeding nearby) and brownish wings (vs. clear wings in the Hiatomyia). I also see thin and straight hind femora with long hairs on the underside (vs. very slightly enlarged dorsoventrally and with short hairs ventrally in the Hiatomyia), but these differences are subtle and may just reflect the angle of view; even if they are real, I'm not sure how broadly they apply either.

Unfortunately I was not able to get a dorsal pattern shot, but I saw it was a hornet-like pattern. I believe the combination of extensive hairs on the abdomen and thorax, along with the all pale face are good for this species.

not sure on the ID.
This fly was in a spatterdock flower and was captured by a bald-faced hornet, which I netted and took the fly off of. The hornet had already killed the fly and bit off its head and one wing, but I though the fly might be something unusual so I kept it anyway.
