Are You sure Theo? It is not registred in our Swedish taxonomic database DYNTAXA. so is not known from Sweden. |

Alas, I disagree with Theo's ID. First, it is a male, in pic 1 there is clearly no theca (compare http://www.discov...riaeformis). The male of C. ceriaeformis has a mostly yellow abdomen. Then, there seems to be no silvery stripe down the lateral thorax, so the key http://www.reposi...ent/507043 leads to C. flavipes. The completely black face, however, is strange and not seen in any Conops species I know... Maybe an aberration? |

No, I am not sure. I have no idea how large the theca should be in ceriaeformis, I supposed it could be small. See Leopoldius for reference, the size is extremely variable. I don't see the silvery stripe either, I noticed that, but this can be due to the angle of view. So though I'd love to see one, I didn't think it would kill the ID. The other arguments are like Sundew's: it keys out to flavipes but it can't be flavipes. Not only because of the black head, but also because of the black scutellum. So, I am lost as well. Probably a highly aberrant flavipes. Theo |

Theca, big or small, is never combined with such a "nipple" on a swollen abdomen tip, which is typically male. The female abdomen is tapering and its tip looks different  C. flavipes can have a quite dark scutellum, see http://www.dipter...to_id=6621. I think I can see a small yellow central spot in pic 2. But the black face is very strange... Edited by Sundew on 11-08-2016 20:06 |

Thankyou Theo & Sundew, probably an aberrant flavipes male then. |

Female ceriaeformis has a strongly elongated third abdominal segment, so as far as there was still any doubt: that it is not. Theo |

There is Conops flavipes var. melanocephala which Kenneth Smith has in his 1969 RES handbook to Conopidae. I notice a Google search of that brings up a couple of similar individuals. |
