Can anyone help me to identify these picture-winged flies I observed today mating (in a threesome…), and males wing waving and fighting by grappling then head-pushing and rising up together. There were a number on an old tree trunk, possibly breeding in crevices in the bark in an ancient woodland. ?? Pallopteridae
