Morley’s Final Catalogue: A local kind among oak; said to feed on Spanish-chestnut fruit, but not in Bentley Woods, where that tree is only too numerous. Suffolk (Curtis, Brit. Fnt.; Wrt); Ipswich, Foxhall, Bealings in 1934-5 (Whit.); several taken sitting on elm-trunks at Campsey Ash on 23 June 1896 (Pyett); Aldeburgh in Julv 1889 (W. G. Sheldon); Tuddenham in the Breck (Nurse, who records nimbana) from West Stow and Livermere singly in 1910 (Ent. 1911, 221). In plenty in acorns, Hemley and Waldringfield in 1935 (Wir).

Recent Status: A common species in Suffolk,

Life Style: A single brooded species with a day flying male that will come to light. It can be found from June to September. The larvae feed inside acorns and sweet chestnuts. They leave the seed fully grown after it has fallen to hibernate in a cocoon in which they later pupate.

Identification: The moth has a whitish ground colour. The wings are mottled grey basally. There are paired costal strigulae that near the apex subtend blueish metallic fasciae that edge the ocellus. The ocellus has black dashes and there are prominent black marks pre-ocellus. There is variable ochre shading terminally.
