Sutton & Beaumont, 1989: Widely recorded and often quite common in vice-counties 62-64, rather more local in VC61 and VC65. This distinctive species is often found in hibernation, either singly or in groups, in sheds, dry tunnels, potholes, and similar places. It is also recorded at sugar, at light, as a larva and has once been found flying in sunshine.
2012 (CHF): Widespread across all of the county. We normally receive 100 to 150 records a year. Most records at light are of single moths but larger numbers are often seen hibernating in tunnels or caves for example 77 at a cave in Wharfedale on 8/12/2006.
