History
Lennon (1863) stated that it was common everywhere around the Dumfries area. Gordon (1919) found it to be common and generally distributed in Wigtownshire, mainly flying after dark in woods and along hedge sides. Earliest date was 23rd September 1910, with the latest on 18th November 1893.
 
William Evans received specimens from Mowat, the Killantringan lighthouse keeper during 1914 to aid his insect migration studies.
 
Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn, Tynron and Castlehill, Dumfries (all VC72). Archibald Russell (1944) listed it as occurring near Gatehouse of Fleet (VC73) during the years 1942-43.
 
During 1975-93 all seven of the Rothamsted stations recorded 250 records between them, showing it to be a widespread moth across the region.
 
From 1996 to 2010 there are few verified records, but those we have came from Kirkton, Durisdeer and Kirkland(VC72).
 
This is the most numerous of the four Epirrita moths.
 
Life cycle
One generation. Overwinters as an egg on bark or a twig. Larvae are present April to June, with pupation taking place underground.
 
Larval foodplants
A wide variety of broadleaved trees and shrubs.
 
Identification
Use the criteria explained in Waring et al (2009) and Skinner (2009) to identify the males, but if worn, genitalia examination is necessary. Even this method is useless for females, but rearing from eggs might lead to the males being determined.
 
Habitat
Mainly broadleaved woodland, but also garden and hedgerows.
 
Recorders' notes
Only take a minimum of specimens for determination at any one site.
