Hello Today I photographed a dung fly(?) on a blossom of a blackthorn "Prunus spinosa" (West-Germany). Unfortunately I do not know, which Species is that. This species was very little...I think 5-6mm. Who can help me and identify this fly? Thanx a lot.-) Greetings Markus Gebel |

1. Crex, I'm not at all Scathophagidae expert! 2. But I think it isn't Scathophaga stercoraria. Such spring and small species may be Scathophaga decipens or Scathophaga obscura. Nikita V Nikita Vikhrev - Zool Museum of Moscow University |

Nikita V I'm sure, it isn't Scathophaga stercoraria. This species is very grey... the bigness from Scathophaga stercoraria is 2x or 3x. I don't know Scathophaga decipens and Scathophaga obscura  Thanx Nikita... perhaps another specialist writes some more! @Crex: Thanx (Danke) best regards Markus |

I am no expert, but every Scathophaga stercoraria that I saw and photographed, was considerably hairier and looked in their entire appearance considerably larger and stronger. Maybe this fly was as big only half as a normal Scathophaga stercoraria was. With the unaided eye I could not identify it her as a dung fly because she was too small. This postal address and the foto-link shows a Scathophaga stercoraria. http://www.dipter...ad_id=4855 How can one explain so big differences? I have some doubt. Thanks Ozerov best regards Markus Edited by Markus Gebel on 03-04-2007 14:43 |

1. To my excuse (I thought it isn't S. stercoraria) I can say that Andrey spend about 15 min before coming to conclusion that it is S. stercoraria. Scathophaga decipens and Scathophaga obscura both has femorae dusting on basal 2/3-4/5, but never completely. 2. S.stercoraria is very variable species, there are boxes in Moscow Zool Museum with hundreds very different specimens of S.stercoraria - yellow and grey, hairy and bold, small and large... So, believ, S.stercoraria is really the best possible answer! Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Just to know something better... Pierre Duhem |
