I can't find anything like this one anywhere, so no clues from me other than it looks like a Syrphid fly.  It was on a Dahlia flower back where there were black aphids, but I had several diffferent insects lay eggs, predators etc. on the plant, including ants. Lincoln UK 7th July 2007. Any clues?  Might help if I add the pic! blowave attached the following image:  [28.03Kb] Edited by blowave on 16-08-2007 22:02 |

Not P. noctiluca, that has two teardrop marks near the top of the abdomen. Pipiza austriaca looks right. Agree? http://www.syrphi...20w01.html http://www.syrphi...20m01.html http://www.syrphi...20m01.html |

Pipiza are extremely difficult to recognize, even with specimen. maybe Pipiza lugubris, it's the most common species in W-Belgium and it has clear dark markings on the wings. but without seeing legs, antennae,... clearly... |

Thanks caliprobola, that is what I needed to know. It seems they are both present here. http://www.dipter...t?id=11275 http://www.dipter...t?id=11283 This site has 4 pages of preferred and no-preferred names, sigh. http://www.dipter...mit=Search |

Now I find that P. lugubris is the non-preferred name for P. austriaca http://www.dipter...t?id=11276 That is encouraging! I can eliminate some, as I already have done, and see what is left.  |

Ah, but now I also find P. lugubris is a separate species also and is just a synonym for P. austriaca http://www.dipter...t?id=11283  |

well, systematics in the genus Pipiza isn't very clear yet (not to say not clear at all...). but as far as i know P. austriaca & P. lugubris are treated seperate in most determination keys (all dutch & belgian keys, including the recent Van Veen book) i have. |
