Yorkshire Status: Scarce and very local resident.

Sutton & Beaumont, 1989: First found at Spurn (VC61) as larvae in August 1949 by H. N. Michaelis (Michaelis, 1951), there is still a thriving colony at this site. Apparently this species is a well-known vagrant in the South of England but it does not seem to have strayed far from Spurn. The only other Yorkshire record is of a larva collected from Sunk Island shore (VC61) in August 1986 (Payne, 1987b) which emerged in 1987 (JP pers. comm.). This is another species which could conceivably occur at South Gare, Redcar (VC62), a similar habitat to Spurn.

2012 (CHF): Still doing well at Spurn but numbers vary a lot from year to year for example a rapid increase to 54 records in 1999, a gradual decrease to 5 records in 2007 and an increase again to 45 records in 2011. There have been no additional records from anywhere else in the county and this is the most northerly colony in the country.
