Sutton & Beaumont, 1989: This moth is reported from only a few sites in each vice-county, but is usually described as frequent or common in birch woodland (though also bred from sycamore (JP pers. comm.)). Whether it is locally common or whether this merely shows the distribution of light traps in operation in the later months of the year is uncertain.
2012 (CHF): It is difficult to tell whether the fluctuations in numbers of this moth are genuine, due to weather conditions or due to variation in observer effort. After being hardly reported in 2008-10, there was a huge increase to 43 records in the warm late autumn of 2011. Probably fairly common in suitable habitat (eg 51 in birch woodland at Ellington Banks on 11.11.2004) and occasionally wandering to gardens.
