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

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 |

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

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

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. Theo Zeegers |

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. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

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 |

Theo, your authority is so doubtless, that if once you tell that elephant is Tachinidae we all have to believe it! Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I have said it before: keep checking ! thanks guys (and IDing Tachinidae remains one of the most dangerous professions on earth !) Theo |
