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 upperwings to the 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, whereay 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).

Recent status: Still common and widespread.
