Loads of these around at the moment. Look like some sort of Beris but I don't recognize the leg pattern. Thanks, Peter peterbolson attached the following image:  [115.46Kb] |

I'm still puzzling over these. The swollen hind tibia of the male suggests Beris to me but I can't find anything in the gallery with the same leg markings. I'd be very grateful for any ideas. Peter |

I am not an expert, but the appearance and the six spined scutellum it should Beris geniculata its!? Nice pics! Frank |

Thanks very much Frank. I can't find any photos here or elsewhere on the web to compare it with but it seems it is common in the UK & is known as the long-horned black legionnaire. |

Using the key in 'British Soldierflies', this looks more like fuscipes. There appears to be a noticeable hump on the inner side of the antennal flagellum viewed from above. The flagellum also seems to be less than twice the length of segments 1+2. |

Thanks empeejay for that interesting suggestion. It certainly looks like the one posted by Tim Worfolk last year http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=22674 but he never received any confirmation and I can't find any other photos of it anywhere. One thing that bothers me is that this is classified as Nationally Scarce in England but seemed abundant at the site I found it, along a woodland ride on calcareous soil next to a river. It would be nice to get further confirmation of this ID. Peter |

I'm sure that's fuscipes |
