Morley's Final Catalogue : A grand insect that is luckily still common everywhere, since its first discovery in ' Suffolk' before 1830 (Stephens iii, 133). it is very keen upon assimilating the mottled-grey of its upper wings to its environment, and hence fond of sitting on stone-church-walls, e.g. at Fressingfield, Cransford and Nettlestead in 1920; another, flying in Hintlesham chyd on 14 August 1921, was snapped up by a sparrow. Sometimes it flies thus in bright sunshine, as in Orford town on 25 September 1929 ; but is usually taken on sugar, whereat it abounds about Bentley, Ipswich, Hemley, Martlesham, Henham. Oulton, Fritton, Gorleston, &c. Larvae occurred at Monks Soham on 17 June 1912. Mr. Platten took a splendid form, brunnescens of Warren (Entom. liv, 162) with quite dark hind wings, near Needham Market in 1905 (now reposing in Harwood's collection at Sudbury).

Wingspan details : Forewing 33-40mm, Wingspan 70-90mm
