(Goeze, 1783)[Synonyms: lamellifera, kuehnella]
This species is locally distributed mainly in the south-east of England, ranging northwards to the Midlands and Derbyshire.
The larva feeds on oak (Quercus) and forms a very distinctive-looking case. In the later stages, the actual case is surrounded by a semi-transparent 'cloak' constructed from scale-like segments of silken material.
Adult moths are white with some indistinct darker markings towards the wing tip. They fly in July and August.
