Hi flyforum, On 16th of August I got one Assilidae on a fence with prey and a little ''fly-hunter'' on these prey. So It are three flyspecies. Anyone familiar with one of these flies? If needed I got some better views or better crops.

An empid (Empis or Rhamphomyia) and what looks to be a ceratopogonid. Possibly the hunter being hunted...

Hi Paul, My idea was that this little fly got attrackted to the scene (when the Empis or Rhamphomyia was already catched). Hereby a crop of my photo; Robert Robert Heemskerk attached the following image:  [166.7Kb] Edited by Robert Heemskerk on 18-08-2012 20:05 Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

In a Dutch forumthread I got the message(Gerard Pennards) that the little fly is Ceratopogonidae and that these flies also drink blood from other insects when they got the chance. greeting Robert Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

If you had inlcuded the second picture in the thread I also could have told you it was sucking hemolymph. From the first image it was hard to tell it was alive.
