Imago

Wingspan 13–16 mm. A variable species with several forms. The nominate form is distinguished from Epinotia bilunana by the grey general appearance of the forewing and particularly the comparatively solid and sharply defined triangular patch on the dorsum at one quarter and black spots at the apex of the forewing.
Another common form is costana in which the forewing is blackish-brown apart from a broad white costal margin which both are sharply defined.
