Thread subject: Diptera.info :: Dasysyrphus?
#1
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

in my opinion this is C. fasciolatum

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

i will ckeck again because now at a secons view I am thinking that I am in a wrong direction...I have compared some pictures of C. fasciolatum with your picture...and you are write ..there are narrow stripes...and there are some other differences...

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!
