I'm in the dark with this one. The pattern in the abdomen it's similar to Melanostoma's sp., but the sculetum seems to have the wrong colour...

Thanks,

This is a Meliscaeva auricollis (in some books still Episyrphus auricollis). A female. In this case with very characteristic spots on tergite 2. A very common species in Spain (as everywhere).
One simple reason why it's no Melanostoma or Platycheirus: the yellowish scutellum.

Thank you Andre. This species is not very common here, otherwise I would have noticed it before. Or maybe it is more common during the winter?

It can be very numerous in early spring yes, though in some years the numbers can stay low. Early spring it's also easier to pick, because there are not so many Syrphids that look like it.
When did you make this picture? Please don't forget to mention that as well.. Wink

Sounds like spring Smile.
Over here it's raining too at this moment. Temperature around 10?C. Much too warm for the time of year...
