The palpus is bright yellow, combined with black scutellum, that should be a big clue. I am thinking Paratryphera. If you still have the fly, check * if the calypter is ‘balloonish’ in a funny way at anterior margin * if the barette is hairy. Theo |

Thank you! The palpus looks blackish to me. I struggle a bit to point out the berette on the fly... Rosevinge |

Yes, palpus is black, which is also possible in Paratryphera. I see some hairs ipon the barette and I can’t make out the calypter shape. Uncertain. Theo |

Ok - I've looked at calyptra in a microscope today and yes - "the calypter is 'balloonish' in a funny way at anterior margin." Rosevinge |

If you could also confirm that the second (apparent first) segment is slightly elongated (at least twice as long as broad), I am pretty confident we can call this Paratryphera barbatula. Theo |

Hmm - Did you mean second antenna segment or second tergite or ...? (Sorry - you are dealing with an amateur) Rosevinge |

O sorry ! Second ARISTAL segment. So not the antenna ! If you have a very close look, you can see that the ‘arista’ in most Tachinidae is actually the third segment of the arista. There are two basal segments. The first one is nearly always extremely short and difficult to see, athe second one might be slightly elongated, in the sense that it is longer than wide.

Yes - the second segment looks elongated - but it is slightly difficult to distinguish the first segment from the second by microscope or pictures. Rosevinge Morten A Mjelde attached the following image:  [216.35Kb] |

Yes ! This is totally OK. For now, very likely Paratryphera barbatula, which is not as rare with you as it is with us. The balloonish calypter is very difficult to illustrate, this it is fundamentally three dimensional. Theo |

Thanks a lot!  I have tried to photograph the shape of the calypter, but the camera has only two dimensions. Easier to see the balloon shape in my binocular microscope. Rosevinge Morten A Mjelde attached the following image:  [292.91Kb] |

Thanks, but I think it can only be seen laterally from above. We are talking about the anterior margin on the calypter. Theo |
