Species Account
Sutton & Beaumont, 1989: Although rather patchily recorded, this species is probably common in most birch woods in all five vice-counties and it is sometimes also found well away from such places. It can sometimes be found more easily on a sheet at light and it often turns up late than most other species (PQW pers. comm.), which may be the reason for the paucity of records.
2012 (CHF): Like other birch-feeding species, this moth is uncommon in the north-west and south-east of the county. Apart from this it is fairly widespread and numbers appear to be stable.
