Epistrophe grossulariae? - male

Epistrophe grossulariae? - Male
Pittsfield/Kirving Park, Berkshire County, Massachusetts, USA

I think this is Epistrophe grossulariae, but I am not sure. One thing I noticed about many of the photos under this species is that some of their eyes are connected and some are separated. Is it common for this species to have either.

Moved from Syrphid Flies.

In family Syrphidae eyes of males are always or almost always larger than eyes of females. Usually male eyes touch, like your fly's. Female eyes never touch in this family.

Male eyes are larger, not necessarily touching, in many families of flies.

"Male eyes are larger"
also true for a wide variety of insect taxa, incl. mayflies, barklice, many nocturnal beetles......

Moved from ID Request.
