Hi Jessica, I've checked it with The Sepsidae (Diptera) of Europe (Pont, Meier) and it looks good! I think you are right with S. thoracica. Greetings, Eric Kloeckner |

Hi Eklans, Great thanks a lot ! Finally, what makes it possible to confirm the species? The bristles of the tibia 1? Maybe also the general color? |

Hi Jessica, it's one of the species with meron glossy in posterior half and pruinose in anterior half, and katepisternum also partly shining and without pruinosity. Adult thoracica differs by having a dark spot at the tip of vein R2+3 and lacking a milky-white patch beyond this. This info + key + figures may be found in The Sepsidae (Diptera) of Europe (Pont, Meier): https://www.resea..._of_Europe Greetings, Eric Kloeckner |

Okay thank you so much. I had seen this document, but I could not see the meron. On the other hand, the katepisternum seems pruinose only on its upper part. So I suppose that seeing this pruinosity is enough even if you don't see the meron ? (coupled with the wing spot) |

What made me think you are right with male thoracica is the complete description in the doc and especially the figure 471 (fore femur).
