Stephane, I am glad you like it. These flies are inexpensive and you don't need a hunting licence, .
Rui, I can compare only responses of some other Coenosia species during taking photos. Bigger species such as C. tigrina and C. humilis are easily disturbed. Smaller ones such as C. agromyzina, C. atra and C. cf. rufipalpis sometimes tolerate even holding a leaf they are sitting on. But I didn't test their tolerance to manipulation so far.
