Yorkshire Status: Fairly widespread resident.

This species was unknown to Porritt and only appeared the county in the 1950s. It was uncommon until the turn of the century but since then has increased in numbers and is now not uncommon in woodland and suburban gardens all over the county. Numbers and distribution are now stable. It occurs in two well-separated broods, the second being a little larger. Second brood moths are smaller and paler. Take care not to confuse this species with the much less common Lunar Thorn.

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.
