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;

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.

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. Wink
