Here is the link to a wikipedia photo of a couple of Bibio cf. pomonae: https://ca.wikipedia.org/wiki/Fitxer:Bibio_cf_pomonae_fg01.JPG Looking at wing venation, the male has r-m vein a bit longer than Rs ("anglicus type"  Looking at wing venation, the female has r-m shorter than R1 ("hortulanus type" So is this perhaps an interspecific coupling? rafael_carbonell attached the following image:  [248.37Kb] Edited by rafael_carbonell on 29-11-2025 20:12 |

I'd rather bet on B reticulatus/varipes for this couple |

Great It would be nice somebody correcting the wikipedia entry. It would be good if someone could correct the Wikipedia entry. On the other hand, I suppose that this type of coupling (which I had never observed in diptera) does not produce fertile offspring. Thanks for the comment |

I've added a comment to the picture. Hopefully the maker of the picture improves the info.

I think that it is a couple of Bibio reticulatus. All veins coloured, costal cell light, as rest of wing membrane, pterostigma well-marked, strongly contrasting. Pilosity of male agrees also with this species. |

B. reticulatus is correct, I think. Compare copula reticulatus: https://diptera.i...d_id=98867 and varipes: https://diptera.i...d_id=98868 Greetings, Eric |

Reticulatus is better than pomonae, so I changed the name on all wikipedia's... Anyone can do this by the way.

For me, it's a solved case. Considering the image provided by eklans, in this species (which is absent where I live, in southern Europe), the male has a venation with the Rs vein shorter than r-m (which I call the ‘anglicus’ type), whereas the female has the Rs vein shorter than r-m (which I call the ‘hortulanus’ type). This contradicts what Duda's key (1930) says for the female. This characteristic is not used in other keys. I will update that in the wiquipedia comment. |
