Moved from Syrphid Flies.

I think it's Melanostoma mellinum. Compare mouth parts.

Also, note halteres.

I think the reason many of your flies look different than other posts is that most of the other posts are of gravid females. Just a thought...

the other
shots I have of this specimen all have a very light green blue hue to the halteres.

Yay! You've got it.
I was shooting on a Russian sub yesterday, and the compact fluorescent bulbs I saw there behind colored glass looked nothing like what came up on my computer. (Camera does not appear to have a Red balancing feature.)

the more gravid they look, the greater the intensity of the halteres, in the examples I've seen. I just looked though my personal files and the gravid look always has a more intense color, and the color intensity seems to increase later in the year as the obvious gravid ones in mid may are light colored and the ones in August are quite bright by comparison.

I have males (eyes touch at top) in my files that are nearly clear halteres, and a very gravid female that is intense.

and probably useful info for others.
