Hi In first happy new year to all dipterist  I have only one picture of this Dasysyrphus. I post in the french forum here http://www.insect...575#214575 We have some difficulties to say friuliensis or venustus. Perhaps it is an other. What can you say ? Thanks for help edith Near paris, april 22th guenille attached the following image:  [127.1Kb] Edited by guenille on 05-01-2008 11:59 |

Well, not friuliensis I think. The spots would be more constricted in the middle. Although the antennae look a bit dark, I think that's the angle of the picture. So I think the antenna is more or less pale, although badly visible from this angle! This is a male of venustus or hilaris, unfortunately the face is not visible. Face with black longitudinal stripe: D. venustus. Without: D, hilaris. Greetings Edited by Gerard Pennards on 05-01-2008 15:57 Greetings, Gerard Pennards |

Hello, I think, it is Dasysyrphus friuliensis. The shape of the markings of the tergites are typical with their u-form. I have some specimen in my collection and they look alike. Greetings Gisela |

Well, Gisela, Maybe you're right, but I'm still a bit weary. The spots look too 'normal' (meaning not hooked enough and not narrow enough) to be friuliensis in my opinion. They should look more like this picture I show here which comes from Van Veen's book! greetings Gerard Gerard Pennards attached the following image:  [79.3Kb] Edited by Gerard Pennards on 05-01-2008 20:28 Greetings, Gerard Pennards |

I agree with Gerard... "If there's any doubt, it's n?t the one"...  Keeping this in mind: the spots on the picture are simply not restricted enough to be friuliensis. |
