Species Account

Sutton & Beaumont, 1989: Widely distributed over all five vice-counties and most commonly found in well wooded areas. The late emergence of this moth means it is not commonly reported, but the larvae may often be found on tree-trunks in June.

2012 (CHF): Doing well across the county but curiously absent from the south-west despite there appearing to be plenty of suitable habitat.
