Hi, This rather small fly I met several times (may be, not the same individual, but the same species, I suppose), and all my efforts to take good pictures gave more or less unsatisfying results. Nevertheless I show them here, as it might be a common species and well known to you. All pics are from the Island of Usedom in August. Regards, Sundew Edited by Sundew on 22-01-2008 15:39 |

Here are pics from another day. (The white lines are spider silk.)

Not Lonchaeidae but Muscidae.

Possibly a male Hydrotaea sp.

Wow - I wouldn't have expected that we came that close to even a species! You are all really great. Now, funnily, I have some more pictures of a black shiny fly with red eyes that were next in my sequence of photoshooting of that day. At a first glance I thought they showed the same fly, but then I saw it sat on another leaf, was smaller, had more distant eyes, and the wing venation seemed to be less complex. So I'd like to show you this fly, too - perhaps this is a lonchaeid to comfort Andre? Thanks for the first ID and in advance for the second, Sundew |

Really no more comments? Now, does the last pic series show a lonchaeid, and how can I discriminate between black shiny muscids (above) and lonchaeids? Sundew |

Yes, I think the last pictures show a lonchaeid. The muscid has bigger, more bristly legs, and there is a well-marked thoracic suture. Also its wings are more widely spread. The lonchaeid has the appearance of a little old lady who doesn't want to cause any trouble. The Hydrotaea is full of confidence - ready for action. This is more obvious in the way they move. The lonchaeid will be rather slow and deliberate, the mucscid more jerky and "on edge". Tony ---------- Tony Irwin |

So sweet of you to try to comfort me... that thought alone comforts me well  PS: did you know there is a Syrphid genus, called Psilota, which looks a lot like Lonchaidae? Try to shoot that one in april/may  |

Many thanks, Tony - this is an excellent description! I should be able to tell the little things apart now. And Andre is happy again, so all ends well with this thread. Cordially, Sundew |
