Hello, I photographed this fly in the Girgini forest, Sardinia (NU), Italy, 900m a.s.l. on May 15th 2025. I found it in the same location as this other Rhagio: https://diptera.i..._id=117056, but this one flew away before I could collect it. Would it be possible to say something more about its identity? Thank you in advance, Emanuele ESant attached the following image:  [299.94Kb] |

Body length? Pilosity on thorax dark, on abdomen light? |

It was quite small. I didn't measure it, but based on the proportions of my hand in the pictures I'd say it was around 6-7mm long. |

I need to check this, but I am currently very busy with pollinators. According to some guy Zeegers & Pollet (2023), corsicanus is endemic for Corsica.... Theo |

R. corsicanus has black hairs on the palps according to Zeegers & Pollet (2023). R. funebris is listed for Italy, resembles corsicanus but has pale hairs on palps and yellow halters - your fly has black or yellow halters? Edited by eklans on 03-02-2026 17:11 Greetings, Eric |

Thank you all for your comments. As I wrote before, this one flew away before I could collect it. The hairs on the palps are pale, but from what I can see the halters are black. |

How reliable is palp hair color in Europe? In western North America some species are variable. |
