Epione vespertaria, the dark bordered beauty, is a moth of the family Geometridae.

Description

The wingspan is 25–30 mm. Adults are sexually dimorphic. In the males the wings are darker and more yellow ocher in colour, while in the females they are pale yellow. Both sexes show on the wings a purplish-grey border of even width (hence the Latin name Epione paralellaria). On the forewings and on the hindwings there is a small black spot. Adults are on wing from the end of June to September in one generation.
