History
Lennon (1863) found it common at Crichton Institution, Dumfries, where he worked. Gordon (1919) found it abundant on most moors, especially after dark on heather blossom in Wigtownshire. Earliest date was 13th July 1905. Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron, Lochar and Castlehill, Dumfries (all VC72) and Colvend (VC73). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
 
During 1975-92 all seven Rothamsted stations recorded it regularly in that period. Then, from 1992 to 2010 it had been recorded from about forty widespread sites from across the region.
 
Life cycle
One generation. Overwinters as an egg on the foodplant. Larvae appear during May and June, with pupation taking place between spun leaves on the foodplant.
 
Larval foodplants
Larvae feed on willows, Aspen and probably other woody plants.
 
Identification
The chevron shaped central cross band gives the moth a distinctive feature. Females are smaller and darker.
 
Habitat
Upland moorland and scrub, but also some lowland habitats.
 
Recorders' notes
Although easily sexed by colour, we have no records of sex, apart from one male in 1915.
