Linnaemya - possibly tessellans but would be nice to key it out and check for picta if you have a specimen  L.picta has been spreading across the UK this year (Kent, Suffolk & Cambridgeshire) so it's not unrealistic to think that it might make the Thames Valley

A Linnaemyia. Might very well be picta. Theo |

@Theo: What might indicate picta from the above photos?

red tibia and yellow humerus. But I'm not sure. Now we mention it, the apical margin of tergite 5 definitely seems reddish int he last pic, which would confirm picta. Olsufjevi and others have a less prominent projecting mouth margin Theo |

Hmm, definitely needs a specimen then ... would be nice to know the exact locality and I could have a look - it must be close to me If it is picta then it is a very exciting record

Thankyou Chris and Theo! I don't have a specimen. I do have this rather blurry photo under a different lighting (for what its worth): tristram attached the following image:  [170.66Kb] |

I've seen a lot of picta this year, though mostly males which are easier to id than this female, but it does look right to me - strong bristles on the lower cheeks. The males have reddish areas laterally on the abdomen-- http://www.dipter...d_id=35154 Steve |

@tristram: Sadly photos won't help much because the features we need to see for a 100% confirmation are too small to show up. If you can PM me the locality then I might be able to have a look but if you can get a specimen then I would be *very* interested indeed - just catch one and I will sort out the pinning etc.

Looks like picta to me as well. Funny, last year tesselans was more common here in Friedberg, this year the opposite! |

Great news - Linnaemya picta has been romping across the country but a specimen from the Reading area would be a massive leap from previous regions I'm hesitant to take the record from a photo but Tristram is going to have a go at catching one for me and I'm going to keep a good lookout in other areas
