History
Lennon (1863) found it in a number of localites in Dumfriesshire in the 1860's. Robinson-Douglas stated that he had found "a lovely, just emerged, specimen of G. papilionaria which was taken at rest on the grass." This was in 1874. Gordon (1919) found it scarce along woodsides at dusk around Corsemalzie (VC74) in July 1898.
 
During the war years F. W. Smith found it at Moniaive in 1939, Closeburn in 1943, and Southwick in 1946. Sir Arthur Duncan (1909-84) also recorded it at Closeburn, as well as at Tynron and Castlehill, Dumfries, during his lifetime.
 
During 1974-90 the Rothamsted Stations, apart from Caerlaverock, noted 170 records during that period. From 1992 to 2010 there were 100 records from widespread sites across the region, with Castle Loch at Lochmaben, Cally Woods and Bargaly Lodge trapping good numbers.
 
Life cycle
Overwinters as a small larva on a stem or twig of the foodplant. Pupates on the ground in the leaf litter.
 
Larval foodplants
Larvae feed on birches, Hazel and Alder.
 
Identification
As one of the largest Geometrids it is easily identified.
 
Habitat
It is a woodland moth, but can also be found on wooded heaths and bogs.
