Species Account

Sutton & Beaumont, 1989: Rather sparsely reported from vice-counties 61 to 64. The records suggest a regular but not common woodland species but it may well be under-recorded due to the present-day emphasis on light trapping rather than sugaring or larvae collecting. The larvae are reported to be often quite common on birch in spring (PQW pers. comm.).

2012 (CHF): Like a lot of moths of broadleaved woodland this species is uncommon in the north west and south east of the county due to lack of suitable habitat. Numbers have increased a little in recent years and it has colonised some new areas.
