First I thought this was a Dasysyrphus albostriatus but the wings seem too coloured. Body length 8-10mm.
Thanks,
Joaquim Gaspar

A
Chrysotoxum, something like
C. arcuatum? Compare this website:
http://www.syrphi...20w07.html. There are lots of good syrphid photos.

I don't think it is a C. arcuatum. Could it be a
Xanthogramma pedissequum?

No -
Xanthogramma has different antennae. You can all those wasp-like species compare on the syrphid website above (

It is one of the Mediterranean
Chrysotoxum species.

Thank you, Sundew and Kahis, after all I think you are right. It should be indeed
C. arcuatum :)

Why do you think so, is there some clear evidence? The yellow stripes in C. fasciolatum seem narrower

well...know I can tell you why I was thinking to fasciolatum....
wing: front margin yellowish with a distinct dark spot....abdomen elongate...now looking to the side you gave us...it could be arcuatum.
I also took in care the yellowish-orange hairs of the abdomen...
But let listen others opinions from others specialists, maybe I am completely wrong...

This is a male Chrysotoxum intermedium (third antennal segment distinctly longer than 1 and 2 together, abdomen seemingly bare, frons black). But, as said before, it is generally believed this 'species' will turn out to be a species complex with more species in southern europe!
