This fly was one of serval in a flower. Then as I was holding the flower (it was breezy) -one crawled onto my finger and stayed long enough for me to get several close ups there too.
Empidiae? -not sure, need to look into.

Rhaphium brevilamellatum or vanduzeei.
Middle femur mostly blackish. Those long hairs on the ventral surface of the fore femur may be the "row of strong black bristles" that identifies R. brevilamellatum. But I'm not sure that's what they are supposed to look like. If those are not the right kind of bristles, this keys to R. vanduzeei based on hind femur yellowish on at least basal half, length 5.0-5.5 mm, hind tibia with about the apical fifth black. Robinson 1964.

Tried to key out using Van Duzee and Curran, 1934, Key to the Females of Nearctic Dolichopus Latreille (Diptera)
https://digitallibrary.amnh.org/bitstream/handle/2246/2080//v2/dspace/ingest/pdfSource/nov/N0684.pdf?sequence=1&isAllowed=y
1b Femora yellow
9b Lower orbital cilia pale
10a Cilia of the squamae black
11a First antennal segment black above
116b Anterior coxae yellow
120b Hind tibiae wholly yellow, or nearly so
125b Anterior coxae wholly yellow, or with a small blackish spot on outer surface at base
126b Basal segment of posterior tarsi largely yellow
132a Basal segment of middle tarsi without a bristle above [as opposed to with a large bristle above near apical third] bolsteri. (Described from Nfld, and not listed in Vockeroth's key to male Dolichopus found near Ottawa)
If I go with 125a (Anterior coxae with a green or blackish streak on outer posterior edge.), that is crenatus Osten Sacken, also not in Vockeroth's key.
Lastly, if I decide at 126 that the hind tarsi are wholly black, or nearly so,
127a 1st antennal segment yellow below
128b front coxae wholly yellow; middle basitarsomere w/o bristle above
129a 3rd antennal segment wholly black ... albicoxa Aldrich (which is local)
So that may be the most reasonable conclusion, although honestly, the hind basitarsomere is half-yellow.

Slightly squished during the catching process but this does appear to be a male.

This specimen was captured in a vial at the same time as a Psocoptera. Within one minute, this fly was lying on its side and handling the Psocoptera between its legs. One minute later the Psocoptera was sucked dry and dropped.
