Thread subject: Diptera.info :: Hecamede and its behaviour

I found some Hecamede specimens feeding and walking on some kind of droping. They were performing, on several occasions, a strange behaviour in which a specimen jumps on top of another but never tries to copulate. Instead it looks like it was trying to "kiss" the other, and then they rolled around, and some squeezes later they would separate. Are they just crazy flies or does this mean something else? Please see the videos.
It looks like H. albicans, right?

Wow Rui those are great videos! I've never enjoyed wrestling until now :D
In the beginning of the second video it looks like he's saying "Come on, you coward! Show me what you've got!" :D

Thank you Lars, I am glad you enjoyed the videos. This is not a common wrestling combat, because in this case the opponents kiss each other.:D
