Thread subject: Diptera.info :: Big Tachinid (?)

Hello!

I photographed this rather large Tachinid (a little bit smaller than Tachina fera, about 15 mm) today here in Ostwestfalen/Germany. Can it be identified from the pics? Thanks!

P.S: A member of my forum posted a rather similar fly (pic taken in Austria/Neusiedler See on May-10-05). Because she does not speak English very well, I ask here for her: could it be the same species (spring generation?)?

Eurithia sp. I think... but I won't go as far as guessing the species :)

PS: the other photo is of an unrelated tachinid :)

It certainly looks like Eurithia.
However, the long appendix to the bend in vein M and the relatively long third antennal segment (compared to the second) indicate Linnaemyia.
Given the locality and the pictures, it should be Linnaemyia tessellans, quite common in autumn on umbelliferae (as nicely illustrated by these pictures !)

Thanks a lot! (I think the other Tachinid from the small image on the link isn't identifiable?)

I'm almost sure that it isn't the same Tachinidae.
I think that Helga's is Exorista.

Thank you very much, Nikita!

Sorry, missed the link.

Difficult to tell, I would need a larger picture.
However, I agree with Nikita that Exoristini is most promising idea.
My guess would be something like Phorocera or Parasetigena.
But we can't be sure at the moment (can't even tell whether eyes are bare or haired). If you want a better ID, please send original picture.

Thanks a lot (also from Helga)! But I doubt that she has a larger picture. This is taken from a video film.
