A low-level immigrant from grassland in northern Europe, appearing on the south coast in recent years in sufficient numbers to breed; this hitherto very scarce migrant has been reported with increasing frequency on the Isle of Wight and in south Hampshire, but it is still quite infrequent, and there are very few records from north Hampshire. Wingspan 41-48 mm. Characterised by combination of median line, apical dash, and dark smoky brown hindwing. Larva feeds on various grasses, such as Common Couch and Cock's-foot, unable to over-winter in significant numbers.
