Nationally scarce (Nb) in barns, warehouses and granaries in Britain, as far north as Inverness-shire, also in woodland on bracket fungus. Only one recent record in Hampshire at Fordingbridge in 1996. Not recorded from the Isle of Wight since 1947. Wingspan 9-16 mm. Very similar to
Cork Moth N. cloacella, which has forewing with patches or irroration of ochreous scales and a well defined postmedian white spot in the disc. (MBGBI Vol 2). Larva feeds on bracket fungus, dried goods, cereals, grain, dried fruit and nuts, causing sufficient damage to be a serious pest in some areas.
