Norfolk status Deciduous woodland. One of several very similar moths which can be difficult to separate, best identified by means of genitalia dissection. In general a little larger than S. ambigualis, with heavier markings, greyer in colour, and stongly chequred fringe.
Around fifteen records in recent years, however Tony Davis (national Pyralid Recording Scheme co-ordinator) remains sceptical as to their accuracy, believing most to probably be S. ambigualis.
Confirmed records from East Winch Common and Tyrrel's Wood in 2009 and Boughton Fen, Ashwellthorpe Wood and Dersingham in 2010. Many more records from 2010 onwards, many confirmed via genitalia dissection which proves the species is increasing in Norfolk.
