3 April, Clitheroe England. Guessing from the Gallery, I thought the pre-sutural dcs too strong for Tephrochlamys, so maybe Heteromyza? Help please, Andrzej! I caught a pair of these (possibly not this pair, as there were several flies together on the birch tree - they seemed to be finding sap), so what should I look for to determine species? Is there an easily available key? Stephen R attached the following image:  [113.85Kb] Edited by Stephen R on 04-04-2010 19:30 |

This is a different fly, but in the same place.

Attach plz, a lateral shot ! and you can also take out the long styli from the male (or separate its from the abdomen). There are two closely related specie: Heleomyza serrata and Heleomyza captiosa. See, plz comments at the Diptera.info: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27888. dr. A. J.

Heleomyza serrata (L.) Epandrium rather rounded than narrowed apically (egg-shaped  ) and styli rather banana-like than hockey stick-like typical characters for H. serrata ! Andrzej dr. A. J. Woznica, Institute of Environmental Biology, Wroclaw University of Environmental & Life Sciences |

If the styli are under the slide are better to compare with others, captiosa is here: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27888 Andzrej dr. A. J. Woznica, Institute of Environmental Biology, Wroclaw University of Environmental & Life Sciences |

Indeed, Andrzej, that photo is very clear. Do you have then a similar photo of serrata?

It was a thread few weeks ago about the serrata/captiosa problem: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27392 . The styli are more thickened but enough for comparison Andrzej dr. A. J. Woznica, Institute of Environmental Biology, Wroclaw University of Environmental & Life Sciences |

Sorry Ruud, I didn't mean anything like that. I found your questions very relevant, and I should have thanked you too. Please continue if you have more to say Stephen. |

At least I only do it accidentally, Roger  If I hadn't been called away for my tea at the critical moment I'd have been more careful  Is that 'Saint' Roger in the Simon Templar sense? |
