Hi Marien Can I suggest you post it to the main 'Diptera Adults' forum here and see if someone like Theo Zeegers agrees? He knows a lot about the distribution of bibionids in the Netherlands and he could maybe give another opinion I am not an 'expert' but recently I took some photos of something *very* similar and here I identified them as Bibio anglicus[/iIf it is [i]anglicus, not hortulanus then it is better - anglicus is much rarer! Best wishes Chris R. So, here is my question: Who can detemine this animal? I found it in my garden which is about one kilometer of the river IJssel in The Netherlands. magnolia attached the following image:  [142.44Kb] |

Bibio hortulanus should have a smaller r-m than base of r4+5 ... in my key at least, which would make this Bibio anglicus wouldn't it? |

hmm... maybe you'r right in this one. But usually B. hortulanus has much more milky wings and reddish abdomen.  Not well visible in the second photo..  |

I thought you were only interessed in wings. But in that case I have another picture. |

It certainly looks like anglicus. The locality supports this ID. Can you please give the locality more precise ? Thanks Theo |

So if they are rare in The Netherlands I have about ten of them in my garden. They fly under the cherrietree and are there still the 25th of April. Theo, did you see the more precise locality I mentioned in an earlier reply? If yes, can you say something about that? Edited by magnolia on 03-05-2008 21:34 |

I have mainly female B. anglicus here in southern England (near river Thames) at the moment - with one male seen today. Saw my first 2 B. marci too, plus a Phasia hemiptera (female) and first Gymnocheta viridis |

Yes, I got the locality, thanks. B. anglicus is maybe not rare, but very restricted in presence: only nearby the larger rivers and in southern Limburg. It can be quite numerous on localities. As you have noted. Theo |
