Myolepta potens is a European hoverfly. The species ranges from France and Germany through central Europe to the Black Sea. It is rare throughout its range and is listed in the Red Data Books of a number of its range states. It is listed by the Council of Europe as a Saproxylic (deadwood-dependent) Indicator species, because its presence indicates that a large quantity of standing deadwood is also present. Two English names have been coined for this species, although neither has gained widespread usage: the Western wood-vase hoverfly and the Moccas hoverfly
