Symmorphus bifasciatus, the willow mason-wasp, is a species of potter wasp, from the subfamily Eumeninae of the social wasp family Vespidae which is widely distributed in the Palearctic region. Description Symmorphus bifasciatus is one of the two small Symmorphus species found in Britain which have a transverse ridge along the front edge of the pronotum. It is distinguished from the other Symmorphus connexus by having denser punctures on the mesonotum, mesopleuron and frons, and because it normally shows yellow patches on the pronotum and scutellum.
