Yorkshire Status: Local resident.

In 1883 Porritt wrote "seems only to occur at Scarborough where it is common". Whether it was undetected at the time in other areas or whether it has spread is arguable, however it is currently quite widespread along our coast from Spurn to Whitby. Further north it is less common. Throughout the country, this is a moth of coastal habitats - rocky cliffs, sand dunes and shingle - but there are some inland colonies. We have two; in Knaresborough where it has been known since the 1960s, records being commoner near the cliffs overlooking the Nidd, and in the Calderdale area where it was discovered in 2000 and where it is undoubtedly resident. Records occasionally come from other inland sites but these may be wandering individuals. The biggest counts are from Spurn, for example 31 on 24/9/2009, but numbers have reduced a little here in recent years.

Sutton & Beaumont, 1989: This mainly coastal species is now spreading again in Yorkshire. It has been re-recorded from its Scarborough haunts mentioned by Porritt (1883-86) and other coastal areas as well as at several new inland localities. This is unusual for this species so far north.
