27 August 2008, NB, Canada.
Ovipositor of a Tachinid. Resembles Celatoria but neither of the 2 species in this genus get as far north as NB.

EDIT: title changed

It is clearly a Blondeliini, so point 119 in key by Wood (Manual).

An obvious possibility is Compsilura: eyes are hairy and I don't see ocellar bristles.
Facial ridge with strong bristles going up.

That's one genus we share.

Yes, the piercer and the saw-toothed bristles where the tergites touch ventrally is quite distinctive of a few genera - should be easy to key out Smile

Damn, now you are really putting me on the spot. At the moment I'm batting 100, I can't do better but if my ID is wrong I'll have mud on my face. So trust me, I know what it is. It's a European Compsilura and we have only 1 in NA.

Compsilura concinnata.
Interesting case.
"Palaearctic. Introduced and established in northeastern USA and southeastern Canada, etc, etc"
(Catalogue of the Tachinidae of America north of Mexico, O'Hara & Monty Wood, 2004)


So that's why it looked so familiar !

If it is Compsilura then they would look great in the gallery Grin

Chris: Attaching a few more photos to show diagnostic characters. Which images would be OK for Gallery? I can, of course 'break up' the plate.

The wing venation, hairy eyes, lack of ocellars and 4 post DC (unusual in Blondeliini): all indicates Compsilura concinnata. So there can be no doubt.

I'd say submit all of them - they all look great and any non-layered photos of Compsilura are unlikely to be better Smile
