Sutton & Beaumont, 1989: Rather sparsely recorded due to its early flight period (January-March) but said to be frequently taken at light, at rest on tree trunks and as larvae (SMJ) in all five vice-counties. The melanic form, f. monochraria (Staudinger), is often most frequent in urban areas.
2012 (CHF): Common and widespread all across the county. Once noticeable change since 2000 is the appearance of this species before the year end often starting in late November.
