The nasty ovipositor (from the host's point of view) should be an important clue.

Phyllophilopsis ?

Theo: Do you still want prints of Gymnoclytia?

Habitus, ovipositor (tubulous, not sharp) and 2 st point to Winthemini, perhaps Nemorilla or Winthemia sp. You might have several species (or genuses) there!

I agree with Jaakko, Winthemia / Carcelia was my very strong first impression. But be not fooled: the new world is a different universe !
(where I have no authority, by the way).
Actually, consulting Wood in the Manual, Phyllophilopsis seems to be a good suggestion. In which case it is Blondellini, which I had never guessed. Note that the pra-alar bristle is invisible in the pic.

Live and learn... Some convergent evolution, I'd say! :o

Theo is right, the ia is too short. (Forum seems to be quite tricky today).

Thanks Theo and Jaakko for all the time you have put into this fly.

Only 2 spp. of Phyllophilopsis in NA and the only species likely to reach NB is nitens.

Wood in the Nearctic Manual shows a lateral view of the face of nitens (Fig 46, p.1216); my fly is obviously not a match. So we go back to Nemorilla or Winthemia?

Would a dorsal view help?

The parafacialia are hairy.
I could have seen that on the second pic.

Why didn't I stick to the rule not to comment on nearctic Tachinidae ?

So Tony, if you please could make a lateral picture of the thorax, we will probably see 5 humerals and a strong prae-alar,in which case Jaakko was right all along.
