horsefly - Tabanus atratus - female

horsefly - Tabanus atratus - Female
Wells, York County, Maine, USA
August 10, 2017
Size: ~1 in.
Found this horsefly on the roadside next to a saltmarsh, struggling to fly. It wasn't injured that I could see but it was unable to fly, so it just hung out on me for quite some time without interest in biting, until I had to leave.
I couldn't find a quick match in the Guide, so I'm interested as to what species this is!

Thanks for the ID! I don't se
Thanks for the ID! I don't see any other images of this species with partly orange wings and silver abdomen in the guide though. Is it just an unusual color form?

 
salt marsh variety
I suspect this fly had some 'problems' during/after emergence such that the wings did not get fully pigmented.
Also, note the yellow hairs at the base of the wings. These seem to be found only in the specimens that breed in salt marshes, have been given the name of variety fulvopilosus.
The silver abdomen is not unusual.

 
Oh, thanks for the explanatio
Oh, thanks for the explanation! That's very cool.
