Hmm.. Exoristini. Could be even one of the smaller Exorista, such as tubulosa or then something like Bessa selecta? Facial ridges look bare, though. |

Thanks Jaakko, I see no suggestions of other Tachinidae experts. So I think they agree with you. A difficult fly again. Best regards, Thijs http://www.tuin-t...engels.htm |

Something of a mystery to me - I don't know anything quite that small but Jaakko's suggestion of Bessa sounds probable - not sure if it is possible to prove it though ![]() Edited by ChrisR on 22-10-2009 21:51 Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

I missed this, but indepedent of Jaakko I reached the same conclusion: Bessa selecta. And then I saw his message Theo |

Is the identification based on the fact that there really isn't much else in the Exoristini that is so small? The antennae look quite distinctive. ![]() Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

That's OK ... I hardly ever see Bessa but they are tiny and they look like this so Jaakko's suggestion seemed a good one. But I was just interested to see if Theo or Jaakko used some other features in their IDs ![]() ![]() Edited by ChrisR on 22-10-2009 22:43 Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

Hi Chris! Just a combination of features: sharp kink in the m-vein, white hairs behind the head, low "short-legged" sitting position and small size. Here in North, B. selecta is the only common one fitting to this criteria, and you have even less species in the UK, so I was encouraged to suggest that. |

you have even less species in the UK Thanks for the explanation Jaakko. I know much more now about my fly. For I could not find much on internet. But I live in the Netherlands ![]() Thijs http://www.tuin-t...engels.htm |
