Tinea pellionella (Case-making Clothes Moth)

Indoor environments like homes, closets, and warehouses where natural fibers and animal products are available.

Larvae consume natural animal fibers like wool, feathers, fur, and silk, as well as lint and hair.

Larvae live within a silken portable case made from materials they eat; adults are nocturnal and do not feed, focusing only on reproduction.

They are serious household pests that damage clothing and upholstery; they provide a benefit by decomposing natural fibers in the environment but offer no direct benefit to humans.
