Interesting photos Rui and Jorge.

I wonder how a fly without wings get's distributed? Did they spread a long time ago when the fly maybe had wing and this is what is left, an endemic population? Or is it maybe the egg/larva stages of their life that allows for distribution possibilities!? Or do they just wander about. I guess that last part depends on how specific their living environment is and what requires for them to survive.

Did you see any more hunting activities or were they just humping around?

thanks crex. I was thinking the same! I think at the moment nobody knows the answer. It will be curious to know the rate of their dispersion and if even they migrated in the past, or not...
No, we didn?t see any more hunting activities. Only busy with the observation of the copula... and with this video >>>
http://www.youtub...tO59JiVAGE it seems that the female is trying to get off terminalia of the male, but this last don't do anything. :| and yes, the male is alive. I keep it alive yet.. :| Very strange this behaviour... female was dragging all the time the male.
I will try to study this fly, but 300 km is not easy to get hands on it.
I will give some indications to Andrade, and Igor, Paul and Adrian can help in this task too. :) They know much better hybotids than myself.
