Yesterday I could observe an interesting behaviour with this little asilid. They were resting and hunting from stones, river inside. On about two or three stones I could see about ten asilids.

Also interesting to observe how other flies approached to them... Comensalism?

A paper with interesting information. Also detected that Stichopogon trifasciatus shared stones when resting.
