Hi, Recently I watched some small black flies behaving like Sepsids but with a different wing pattern. I suppose they are Ulidiidae. Please help with ID! Many thanks, Sundew Sundew attached the following image:  [176.64Kb] Edited by Sundew on 31-07-2012 16:07 |

Wow - a new family for my collection (now I have 72)! I wonder why I have not seen one before, as Fabaceae is a very common family. And it is funny to learn how many small flies mimic Sepsids (or vice versa  ?) Thank you very much, dear Valery. |

But only in a very short span of their life ants are able to perform wing waving  . |
