It has not been recorded from France and Slovenia, but this may simply be due to its being overlooked or confused with similar species than being genuinely absent, as it is found in the neighboring countries.

But this synanthropic moth has been distributed essentially all over the globe, though many such introduced populations are not stable for long periods of time.

The forewings are irregularly mottled black, white and grey, resembling close relatives such as the cork moth (N. cloacella).

[8] Larvae in association with humans will feed on a variety of dry organic material, such as dried fruit (e.g.bilberries, Vaccinium) and mushrooms, cereal and legume seeds, flour, Topinambur (Helianthus tuberosus) stalks, and even cork (e.g. corks of wine and champagne bottles) and the ergot fungus Claviceps purpurea.

Further records have been claimed from Capsicum annuum fruit, poppyseed (Papaver somniferum), bitter almonds (Prunus amygdalus amara) and beeswax, but it is not clear if they refer to this species or the cork moth.
