(Curtis, 1832)Wingspan c. 18mm
This rather distinctive species occurs mainly on rocky coastlines, from the West Country northwards to north-east England and Scotland.
The larval foodplant is scurvygrass (Cochlearia officinalis), the larvae feeding amongst spun leaves and flowers.
Like several related species, the distinctive pupal cocoon is formed from a network of silk.
Adult moths fly from July onwards, and overwinter in this stage, occurring on the wing until April.
