Hello!

One of the most abundant Tachinids here in the moment (Ostwestfalen/Germany). This is Phania funesta, right? Length about 4-5 mm.


Also very numerous: Dexiosoma caninum and Epicampocera succincta:

It's a nice guess (small, black with silvery face and outstretched wings)but I don't think it is Phania funesta because the angle in vein-m is too sharp and there is silvery dusting on the abdomen. Have a close look at the middle photo here http://tachinidae...rcno=10601.

I would like to see a few more angles but perhaps it is more likely to be Phyllomya volvulus - see http://www.dipter...to_id=1078 ... but I am not sure ... without seeing a few more photos :)

Thanks for the links! I had both species here already (P. funesta being one of the most numerous Tachinids), but about this one I was not sure. It seemed a little too large for Phania funesta, but a little bit small for P. volvulus. The main reason, why I suspected P. funesta after all was its attitude of holding the wings spread in the position typical for this species. But Phyllomya volvulus seems to do that, too... Unfortunately I have only this picture.

It's a Blondeliini, I'd say, either Gastrolepta or Medina.
Can't tell from this shot.

Thanks! I will take a look, which species from these geneara occur here. Both genera are new to me...

On second thoughts, given the dusting on the thorax, it can't be Medina.
So my suggestion is Gastroleptra, only one species: anthracina.
A male
