Yesterday. La Pe?a, Huesca, NE Spain. 500 meters high. Mix of mediterranean and mountain climate. Habitat: in the side of a lake, between the segdes (Phragmites australis), in a company of high numbers of Calopteryx xanthostoma. Size: more or less the same than Episyrphus balteatus.

The picture is not good, the ligh was in a wrong angle and the photo results very darkened. But you can see the stair design in the abdomen.



What can be?

Thanks.

Meliscaeva auricollis?

Or it could be a Platycheirus, such as P.fulviventris for instance.

Thanks to both. I let it as Platycheirus then...?

---

My first and second guess: Platycheirus scambus and fulviventris :)

Thanks.
