Size 7 mm. I think it's a close relative of No. 1.

I agree with your view that this is related to #1 - perhaps male & female of the same Parhamaxia spp. One of the unusual features of Parhamaxia is apparently the presence of a 'costigial bristle' (a feature normally seen in Phyllomya). If you're puzzled then don't worry - so was I - I had to look it up in the figures. It is the strong bristle clearly visible here near the base of the wing, close to but not on the costa.  |

Many thanks Chris - ventral views of abdomen for this one, too, let me know in case they might be useful. It was very difficult to shoot these two... |

It is a male of Halidaya aurea Egger, 1856, a rare nice species known from Europe to Japan. Best regards Peter |

Yesterday I was lucky enough to take some pictures of this fly in nature (around 7 p.m., exactly the same place and almost the same date , mostly on small Populus tremula).

Please ... tell me you got a specimen!  Looks identical to the last one - nice find  Did you just see one or were there more individuals? Edited by ChrisR on 10-07-2008 19:08 |

No, sorry Chris  , he disappeared, maybe it was late enough but there was some Thelaira and C. silacea still around. I'm not sure about other individuals, he kept landing on and taking off several leaves he preferred and messed with other flies in the air but I couldn't discern whether they were of the same species. Going to re-visit the place soon and check once more. |

I've caught two males today - an impressive case of strict habitat preference - these are for you Chris . |

 wow! Thanks This fly must have a very interesting distribution, to be considered so rare. Perhaps the vast tracts of Russian forest hold many entomological secrets |
