Is it possible from these bad pictures to tell which family and eventually to which genus this about 3 mm long fly belongs. It visited droppings from fox that ate blueberries. Photos from 31 july 2013 Nattsjön 62 N, E 17 Ångermanland, Sweden. Thanks for your help in advance Regards Kurt Holmqvist kurt attached the following image:  [106.77Kb] Edited by kurt on 08-08-2013 19:15 |

I would say Sepsidae and Sepsis (cf. punctum) |

Thanks to Roger and Piet. I thought that these legs was to thick for Sepsis? Kurt Holmqvist |

In the second picture you can see that segment 1-2 of abdomen are narrow and constricted and tip of vein R2+3 has a black oval spot. These are typical characters for Sepsis. |

The Sepsis in Scandinavia are far more slender and darker in leg colouration than the specimen in these pictures. |

Thanks for your comment Gunnar. It certinly looks like a Sepsis but the coloration and thickness of legs feels wrong. Kurt Holmqvist |

I examined some material from my collection now. I have specimens with orange legs belonging to Sepsis punctum and S. violacea from Dalarna region determined by Ozerov. This is not so far away from Ångermanland. In punctum smaller specimens have more dark legs, there is the opinion in literature that specimens from dry habitats tending to have black legs, and all of my very large males have those orange and in comparison thick femura as shown in your pictures. Finally I have a female with orange legs from Dalarna determined as S. punctum geniculata. S. geniculata is synonymised in 2004 with punctum by Ozerov. I still say Sepsis cf. punctum to your fly. |

Sepsis punctum can be quite variable with big males that have orange syntergite and smaller darker specimens. It's a little scary when luteipes and violacea is quite similar. I have records for S. cynispa, S. flavimana, S. fulgens, S. luteipes, S. orthocnemis, S. punctum and S. violacea So there are already lot of Sepsis known from Ångermanland |

Thanks to Nils and Piet for your comments and explanations. I agree with you that it is a Sepsis and call it S. sp. Kurt Holmqvist |
