14 September 2007, New Brunswick, Canada. Both flies collected on trail in dense woods.
There was some discussion recently about the usefulness of wing venation for diagnostic puposes.
2 'types' of Tachinid wings. Top:
Phasia sp.; bottom
Tachina sp.

that second venation in Tachina.. is something! I never saw such unusual deviation in M vein.

I compared a couple of
Phasia photos of mine,
P. obesa and
P. pusilla. They differ in some ways. The petiole is longer in P. pusilla.

Wing of a North American
Microphthalma sp. (Tribe: Dexiini) showing long appendix of vein M (A) at its bend; similar to that of the European species.

Another configuration.
Note the right angle bend in vein M followed by a long smooth concavity before straightening to join wing margin just behid apex of R4+5.
Also note the sinuous curve of cross vein dm-cu (discal medial-cubital)
