In the 20th Century, this species was a common immigrant from northern Europe, in many years arriving in southern England in sufficient numbers to breed. This century saw an increase and it continues to extend its range northwards, probably in response to climate change. In Hampshire and on the Isle of Wight, similarly it was once a scarce migrant which is now established and quite common along the south coast of Hampshire and throughout the Isle of Wight, and increasingly further inland, although still relatively scarce in VC12. Wingspan 34-40 mm. A relatively well-marked and distinctive wainscot. Larva feeds on Marram-grass, and away from coastal habitats, on other grass species.
