Hi Fly-reader, What kind of fly is this? Is it Sepsis fulgens? It's got a white spots beside of the abdomen and thorax. Also some black hairs on the thorax. On the legs (and some in the wing) you see yellow pollen from Tussilago farfara. regards, Robert Heemskerk Robert Heemskerk attached the following image:  [66.5Kb] Edited by Robert Heemskerk on 08-04-2006 08:45 |

Here you see the white spots on the side of the thorax and on the side of the first abdomen.

Hi Robert, It's a Sepsis sp., however I think one should have more details to identify a female specimen to species level properly. But one of the others may think otherwise. Jan Willem |

Hello, My impression is that the "white spot" on the abdomen is in fact the haltere of the Sepsis. But that does not give me its name meanwhile !

Hi Robert. 1. In Sepsidae, males have row of spines on ventral side of f1, so I think that yours is female. 2. To tell you truth I doubt that it is S. fulgens. I can see on photo only 1pair dc. If it is realy so (1dc) - than in Europe it may be S. punctum only. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hi! Nikita Vikhrev wrote: 2. To tell you truth I doubt that it is S. fulgens. I can see on photo only 1pair dc. If it is realy so (1dc) - than in Europe it may be S. punctum only. S. punctum is normally much paler than this with mostly yellow legs. The 2nd photo clearly shows a second, slightly smaller pair of dorsocentrals. PS. Nikita, thank you very much for Ozerov's book & catalogue! Kahis |

Today I took Martha's, Nikita's and Kahi's comments with me in the field and looked at several Sepsis flies. So I found a male Sepsis punctum (Sepsis fly, yellowish legs and paler, with rowof spines on his front legs and one pair of dorsocentrals) I'll post two pictures, trying to convince you and get my first 'Sepsis diploma' This fly got hair on the abdomen and the thorax is silverish Under thorax and abdomen it seems to be white. greeting and thanks again for your reaction!
