This one is photographed this evening in a big group over and near a white fungus that could be Coprinus comatus (white, hairy, laminated, long...). The fungus was growing under a dead trunk of Populus nigra in a river forest (Populus, Fraxinus, Tamarix, Salix) at Ebro river, Zaragoza, Aragon, Spain. The flies sizes about 6-7 mm long.

What can be?



Thanks ;)
