Species Account


Sutton & Beaumont, 1989: A local and mainly day-flying moth, seemingly now quite scarce with few records since 1970.

2012 (CHF): A National BAP species which has declined all over England though it is still doing fairly well in the north-west of Scotland. The only post-2000 records have been from its old site at Bishop Wood and in 2011 from an unexpected new site in VC62 near Boltby.
