History
First record came from Archibald Russell (1944) who listed it as occurring near Gatehouse of Fleet (VC73) in fair numbers on Bilberry during the years 1942-43.
 
During 1976-90 there were thirty-six records from all of the Rothamsted stations. During 1978 it was also found at the Devil's Beef Tub, Dumfriesshire by K. P. Bland.
 
From 1995 to 2010 there were only eight records and those were from Shinnel Glen, Loch Skeen and Corserig Hill in Dumfriesshire, and, Mersehead RSPB, Carsfad at Dalry, Craignell and Bennan in Glen Trool in Kirkcudbrightshire.
 
Life cycle
One generation. Overwinters as an egg on the foodplant. Larvae are very distinctive from the other Epirrita species and are present mid April to the end of May.
 
Larval foodplants
Bilberry, Heather and sallows.
 
Identification
The male and female of this species cannot be told with certainty from Autumnal Moth by genitalia examination. But a smaller Epirrita moth flying in August and September over acid heathland or moorland are probably of this species and can be recorded as such. Although Autumnal Moth flies from late September.
 
Habitat
Moorland where tall heathers are prominent.
 
Recorders' notes
The use of Waring et al. (2009) and Skinner (2009) to determine will suffice for recording purposes.
