Illustration from John Curtis's British Entomology Volume 6

The wingspan is about 18 mm. The head is whitish, with some dark fuscous hairs. Tuft of palpi very short. Forewings light fuscous, much suffused with whitish - ochreous, with scattered dark fuscous strigulae; an ochreous-whitish dorsal streak from base to tornus, upper edge with triangular projections before and beyond middle, towards base blackish-edged. Hindwings are light grey. The larva is green; spots black, conspicuous; head and 2 black-speckled.[1]

Adults are on wing from July onwards, and overwinter in this stage, occurring on the wing until April.

The larvae feed on Cochlearia officinalis.
