Hello, this tachinid is from july from the alps on about 2000m height. Is was about 1cm long. What fly is it? Perhaps some Tachina species? Or a Nowickia species? Thanks, Michael Michael Becker attached the following image:  [68.46Kb] Edited by Michael Becker on 30-01-2009 20:03 |

Well, more llike 15 mm. or larger. It is a Nowickia or a Peleteria. In both genera there are strong hilltoppers (N. reducta, P. prompta). First impression is Nowickia, however, the abdominal pattern does not look familiar. Theo |

Hello, thanks for your answer. I have changed the subject, so perhaps we can catch attention of someone who specialized in Nowickia species ;-) Michael |

I think the problem is that we have artificially high contrast caused by the dark fly sitting on a pale stone in bright sunlight. I have put it into PhotoShop and played with the levels to bring out any more detail in the abdomen and the wide black mark on T4 becomes much narrower on T5 and there is clearly more orange on the sides of T5. Not sure if that helps  |

so I change my opinion in favour of Peleteria prompta. You can see marginal bristles present on syntergite 1&2. In Nowickia, that would imply marklini. However, marklini males have the vertex much narrower. So it can't be Nowickia. Moreover, it agrees with males prompta in my collection. You can't see the Peleteria-bristles, but this might very well be due to the angle. Theo |

Hello Chris, hello Zeegers, thank you for your efforts. I have to admit that I can't really see the bristles or the narrowness or wideness of the marks on T4 and T5. Do you thing Peleteria prompta is sure enough for the gallery? This species seems to lack there. Michael |

I'm 95 % sure. Peleteria prompta is only seen hilltopping, therefore, rather difficult to get. If this was at a very hilltop, that would greatly support the ID. Theo |

If this was at a very hilltop, that would greatly support the ID. It was a ridge with nearly the same height as the sorrounding peaks (about 50 or 100m lower), definitively not a valley or a slope. I think, this place would support P. prompta. Greeting, Michael |

Yes, it does. All is well that ends well. Theo |
