First I thought this was a Dasysyrphus albostriatus but the wings seem too coloured. Body length 8-10mm. Thanks, Joaquim Gaspar Alvesgaspar attached the following image:  [137.87Kb] |

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

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

No - Xanthogramma has different antennae. You can all those wasp-like species compare on the syrphid website above (http://www.syrphi...ege-chrys/). Sundew |

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  Joaquim |

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... Amalia |

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! Greetings, Greetings, Gerard Pennards |
