Nationally scarce (Nb) in barns, warehouses and granaries in Britain, as far north as Inverness-shire, also in woodland on bracket fungus. The only records in Hampshire are from Fordingbridge in 1996 and in West Park, in the part of modern day Hampshire that is in VC8 Wiltshire, in 2002. 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.
