This fly was about 6mm (Belgium, 14-08-2008). Is it a male of Anthomyiidae ? Christine Devillers attached the following image:  [135.04Kb] Edited by Christine Devillers on 23-11-2008 18:35 |

It's a male of Anthomyia, liturata group which don't have the black and white thoracic pattern of the pluvialis group. It is either Anthomyia liturata RD or confusanea Michelsen, the difference is in the genitalia. How do I recognize these two species? Because the crossveins are somewhat clouded which is unusual in Anthomyiidae. A. liturata is the more common species. |

Thank you, Michael! 26 Oct in Azerbaijan I collected Anthomyiid with plumose arista and infuscated crossveins. Now this mystery is clear to me Nikita Vikhrev attached the following image:  [127.47Kb] Nikita Vikhrev - Zool Museum of Moscow University |

Thanks a lot for those explanations. I saw several male, and in FE they don't mention A. confusanea in Belgium (but perhaps not correct !), so I suppose that it is probably Anthomyia liturata. |

Your photo Nikita shows the typical 5th sternite in profile of these two species, projecting downwards. A. confusanea was only separated from liturata in 1985, so the distribution in FE is probably incomplete, based on dets by Michelsen and myself. I have found it flying with liturata in quite a few localities. The female (and to some extent the male) has traces of orange on the hind tibia. |

Thanks again. I didn't see traces of orange on hind tibia, and I've seen in your key that, on mid tibia, liturata has generally 2 ad setae (confusanea generally 1 ad setae). If the arrows on the following pictures show the 2 ad setae, could it be liturata ?

Thanks Michael. As I don't see Anthomyia liturata in the Gallery, I'll submit my photos. |
