Yorkshire Status: Uncommon and fairly widespread resident.

Sutton & Beaumont, 1989: Widely distributed and sometimes locally common in an area for a few years. Many populations seem to either be transitory or subject to large variation in numbers.

2012 (CHF): In the Rothamsted data this species had declined by 98% between 1968 and 2002 making it the moth with the biggest drop in numbers. This seems to have been most marked in the south and numbers in Yorkshire were doing fairly well until 2009 when records dropped by a significant amount. This species may be prone to major fluctuations and it is interesting that Porritt regarded it as generally scarce in 1883 which he altered to local but not uncommon in 1907. Records are currently spread all across the county with the exception of the far west.
