Hi all,
I hope I don't abuse wiht all my posts, and so many questions...

I suppose this fly is a tachinidae : why not Exorista sp ?
Do you think I'm far ?

Taken in south of France, Sainte-Victoire's mountain, on 9 june 05.

Regards,
Stephan

Definitely looks like a tachinid ... and Exorista isn't a bad guess. but my knowledge of southern European fauna isn't good enough to say for sure. :)

It is, ol course, very difficult to identify Tachinids from pictures.
You can forget about keys, so you simply need to know the species at once.
The wing venation might suggest Exorista, with the long appendix to the bend in vein M. However, there are other genera with such long appendices, for instance Linnaemyia.
In this case, I think it is female Linnaemyia because of the low ratio between the 2 and 3 antennal segment (2 quite long), which is quite ununsual in Exorista. Linnaemyia has strongly reduced palpi, so if you collected the fly...

If it is Linnaemyia, then the species looks to me like soror (sister species of comta). An educated guess.
Peter Tschorsnig has the expertise to confirm / deny
So Peter, please help
