I think it's a Ceratopogonidae, about 5mm, can it be named? Found yesterday in Zeist, Holland hedy2411 attached the following image:  [47.73Kb] Edited by hedy2411 on 20-07-2014 22:26 |

Are you sure about size? It looks like Stilobezzia which is much smaller. |

This is consistent with Stilobezzia antennalis, a holarctic species originally described from North America. I do not know what the other European species look like. If you can find a description of flavirostris, compare that. The several species of subgenus Acanthohelea are less likely. |

I found a useful reference. The female Stilobezzia flavirostris is for practical purposes a larger antennalis. (Male genitalia are distinct.) I could not tell the difference from this photo. Assuming your size is an overestimate, call this Stilobezzia (Stilobezzia) cf. flavirostris. Reference: Alwin, Alicia and Ryszard Szadziewski. 2012. Biting midges of the genus Stilobezzia Kieffer, 1911 in Poland (Diptera: Ceratopogonidae). Polish Journal of Entomology 81:365-382. Edited by John Carr on 19-07-2014 01:28 |

Hello John, Thank you for all your efforts to name my fly! It sure looks like Stilobezzia, it seemed to me it was rather big, maybe 4 mm then, I'm not sure. I have another picture, more or less the same, can it help..? Regards, Hedy hedy2411 attached the following image:  [61.95Kb] |

I can only refer you to the paper I mentioned above. It has all I know about Stilobezzia flavirostris. |
