Like other notorious clothes moths, this species was widespread, abundant and troublesome. But now it has become scarcer since the introduction of artificial fibres and modern moth proofing insecticides, because the larvae don't grow well on thoroughly cleaned wool. Recently found more and more in owl pellets, but it's still very rare in our country.
The species moves into man-made habitats when the opportunity arose.
The adults come occasionally to light.
The adults have mainly been observed from the beginning of May towards August. Observations outside this period are frequent since they often live indoors.
The larva feeds in a portable silken case and lives in: birds nests, on feathers, carcases, animal fibres, owl pellets, wool, spices, hemp, tobacco, fur and stored vegetable materials.
