Sutton & Beaumont, 1989: One of our commonest moths, recorded widely over all five vice-counties, well up the valleys and on the higher ground. Dark specimens are frequent, for instance at Harmby near Leyburn (VC65) approximately fifty percent of moths are reported to be melanic (FBS pers. comm.). However, no recorders have specified which form (ab. infuscata (White) or ab. aetbiops (Staudinger)) has been noted.
2012 (CHF): Extremely common and widespread all over the county in a variety of habitats. Numbers are stable. Some of the biggest counts come from upland grassland areas eg 535 at Ballowfields LNR in Wensleydale on 6.8.2010.
