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

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.

---

Rhagio corsicanus? Do you agree, Theo?

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....

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?

---

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.

Neither do I - but it's quite distinct and R. corsicanus seems to be an endemic species in a limited area.
