Habitat

Human-associated environments including houses, warehouses, and facilities. Favors dark, undisturbed locations such as unheated basements, attics, and stored product storage areas.

Distribution

distribution associated with human commerce. to Europe; now established across North America, Australia, New Zealand, and other regions. Records include Austria, Belgium, Britain, France, and numerous other countries.

Seasonality

have been observed emerging in early June following larval development through winter months. Activity likely year-round in heated indoor environments.

Diet

Keratinous materials including wool, fur, feathers, and hair; also dried material such as dried mint (Mentha). possess specialized digestive (γ-glutamyl transpeptidase/isopeptidase) for breaking down isopeptide bonds in keratin .

Life Cycle

with larval development occurring through winter months. emerge in early summer (June) based on rearing observations. Copulation may last up to 24 hours. Females lay on substrates after mating.

Behavior

Young exhibit negative . Males locate females via olfactory cues; distance increases from minimal range to approximately 38 cm after females extend their ("lock position") 2–3 days post-. Males possess specialized sensillae in -free grooves on antennal undersides for detection. Females show fewer and shorter antennal sensillae. Males can mate with at least three females. Post-copulation, females become positively geotactic and move to substrates for . exhibit with massive proliferation potential.

Ecological Role

of keratinous and dried materials in human-modified environments. Pest of stored products and collections.

Human Relevance

Significant pest of stored products, textiles, and museum specimens. cause severe damage to woolens, furs, dried herbs, and other stored materials. One documented reduced 50 kg bales of dried mint to within months. Control requires proper , , and in domestic and commercial settings.
