A common species throughout Belgium, in some places a common household pest.
Native
The eggs are oviposited on or near dead or decaying organic material.
Pupation in the larval feeding place, in a tough cocoon of silk mixed with the material on which the larva has fed.
The adults are active during late evening and night and readily come to light.
The adults have been observed all year round, most specimens however in July and August. There are probably several generations a year, especially when the caterpillars can develop indoors.
The larva lives on seeds, dried plants, wool, cotton, skins, dead insects, frass, books, in birds nests, etc.
Houses, barns, storage rooms, nests of birds, abandoned gardens and forests.
