The members of the genus Milesia are large, wasp-mimic, saproxylic hoverflies. In Europe, only two species occur: Milesia crabroniformis and M. semiluctifera, but their distribution is still not sufficiently known, especially in eastern Europe. In the Balkans, Serbia is the country with the best-studied hoverfly fauna, while most of the other count...
