Hello, Is it possible to say which Bolitophila sp. this is? It was on 28th January 2010 at the edge of my pond. Size I'm not sure of, anything from 7-10mm. Near Lincoln UK. Janet

Perhaps B.saundersii most likely, that's probably as much as you can say. |

Thanks John, I had seen a drawing of a male B. saundersii on delta-intkey, the wing venation looks good for that. http://delta-intk...ent581.jpg If you think it's a probability too I'm happy with a cf. which is not so bad for one of these.

Shame the antennal pubescence isn't visible - its long in saundersii. |

Aah, it might not be saundersii then. I had noticed the long hairs on the drawing but wasn't sure if the female would have them too. I cropped part of the antennae closer.. actually it wasn't in a good state, it looked like it had just emerged but wasn't making it. We had very cold weather then. If it had longer hairs they could be stuck down but I think I can see short hairs. blowave attached the following image:  [116.69Kb] Edited by blowave on 25-11-2010 22:43 http://cubits.org... |

I'll have to have another look at the key. |
