Hai Bruce,
This remembers me of Family Tachinidae, and possibly subfamily Phasiinae.
An other option is something like Gymnosoma sp. (also Tachinidae), that is a genus also with 6 species in your part of the world :-))
But I don't know for sure! This family has a lot of genera, and are sometimes quite difficult to identify.
So, it MIGHT be Tachinidae, subfamily Phasiinae.
These are mostly parasites of true bugs.

Greetings

It looks indeed like a Tachinidae to me.
I am no specialist in the Nearctic world, so I can't give you a genus.
It might very well be a member of the tribe Phasiinae, as suggested by Gerard.
You could try the old key by Coquillett (1897).
Good luck

Hi

Personally, I am not sure about this being a tachinid. With its wing posture, grey dusting and fondness for daisy flowers it certainly reminds me of a Phasia obesa. But the wing venation has vein-m reaching the margin and not forming a petiole (which all/most Phasiines have). On a more worrying note I cannot see any subscutellum. Granted, that would be hard to see anyway - but perhaps the original poster has more photographs?
