Yorkshire Status: Uncommon and fairly widespread resident.

Sutton & Beaumont, 1989: There are odd records in the County going back several years but this species was not definitely admitted to the County list until fairly recently, as it is easily confused with the dark form of S. lunularia (Hubner) which occurs in Yorkshire.

Beaumont, 2002: Now recorded widely and commonly, especially in the south.

2012 (CHF): This species has continued to do well and can now be found in good numbers all across the county.

Recorded in 144 (72%) of 200 10k Squares.
