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

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 Grin?) Thank you very much, dear Valery.

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