A tachinid fly. When I saw it I thought it was a large Sarcophaga. A little similar to Phorocera assimilis, P. grandis on http://www.dipter...d_id=54493 But larger and darker. Length 14 mm. Bergen, The Netherlands. Photos 14-5-2013. Regards, Thijs thijsdegraaf attached the following image:  [83.32Kb] http://www.tuin-t...engels.htm |

Phorocera assimilis, indeed one of the few tessellate Tachinidae that is as elongated as a Sarc. Theo |

Maybe that's why I've seen it never before in the garden. Thanks Theo. Regards, Thijs http://www.tuin-t...engels.htm |

Well, study it and you will pick it out easily: * eyes darker red than Sarcophaga * eyes hairy Theo |

Ph. grandis is difficult to tell apart. Needs a pairwise comparison (at least for me). |

I know Theo. But when I walk in the garden I take no attention to Sarcophaga. There are so many. On a distance I hadn't recognized it. I read the differences between these two species Jaakko, but it is difficult to me. Grandis: fore tarsus as long as 2/3 of the fore tibia.................... Obscura, similis: fore tarsus as long or almost as long as the fore tibia................ Regards, Thijs

Jaakko Of course you are very right, I cannot tell the difference between assimilis and grandis in this picture. Assimilis is pretty common and grandis is very rare, so that is why i called it assimilis Theo |
