A rare Red Data Book species, on grassy slopes and sea cliffs, on the Isle of Wight, and on the southern coasts of Cornwall, Devon and Dorset. On the Isle of Wight, although the number of colonies is small, the moth is firmly established in the south and west of the island, and the outlook appears good; also probably still frequent along the Freshwater cliffs and occasionally a little way inland. In Hampshire recorded for the first time at Sandy Point, Hayling, on 12 September 2010, most likely representing a wanderer from the island. Wingspan 28-36 mm. Larva feeds on various grasses, including Common Couch and Annual Meadow-grass.
