Species Account

Sutton & Beaumont, 1989: Often the first of the larger moths to emerge, this species is generally common in areas of well established birch but scarce elsewhere. Recorded from all five vice-counties, although only in the west of VC61.

2012 (CHF): The comments in 1989 are still true. It can be very common in birch woodland in March but uncommon elsewhere.
