Phasia
Nikita Vikhrev
Moscow region, 23 aug, 4-5mm.
Female of Phasia obesa?

I'd say so, but you know what my record on Tachinidae is like! Pfft

Late summer is good time for bad Tachinist, grace to somehow recognisable subfamily Phasiinae!

Well, I see only 1 row of bristles on the parafrontalia and the genitalia suggest pusilla, so my guess would be pusilla

Theo, halteres are yellow!

Theo - I thought that the ovipositor in pusilla curved downwards - have I got it wrong? Frown

I'd go with P.obesa (female) - yellow hairs on the gena & yellow haltares Grin

Maybe the first picture fooled me ?
The shape of the tip of the ovipositor is not like obesa, there is a downwards oriented 'pin'-thing. Or is this something behind the ovipositor ?
The halteres seem to be yellow, though very out of focus, I'n not sure.
The genitalia resemble most Ph. pandellei.
However, I am not going to give such an extreme ID on a photo, not matter how good the effort, Nikita.

So, let's wait for the specimen.

Thank you Theo.
OK, you'll get speciment mid-september. I have to say that this time I'm 100% sure, that 1-st and 2-nd photo are of the very same fly.

Hi Nikita,

I noticed this summer in Siberia that Russian have a good sense of humor!

I only just noticed your left new picture.
It is clearly not subgenus Hyalomyia, so all my contributions are wrong.
Except for the part that I might have been misled on the genitalia in the first picture.
So it should be obesa, chris was right all along!
Still nice to have a look at the real material.

Theo, your authority is so doubtless, that if once you tell that elephant is Tachinidae we all have to believe it!

I have said it before: keep checking !

(and IDing Tachinidae remains one of the most dangerous professions on earth !)
