Similar species.

Combination of the structure of valvula 3, nearly completely black coloration, and the large size (9-11 mm) enable easy identification of the females. Males are best recognised by examining penis valves. Interestingly, a reared male specimen from Finland (http://id.luomus.fi/GL.5198) has vein 2r-rs present on both wings.
