Case-bearing clothes moth (larva)

Indoor environments, specifically closets, wardrobes, and upholstery where natural fibers are present.

Keratin-rich materials including wool, fur, feathers, hair, and silk, as well as some synthetic fibers blended with natural ones.

Larvae construct a portable silken case incorporating debris and fiber fragments, which they drag with them as they feed. They typically pupate inside this case.

Risks include significant damage to clothing, carpets, and valuable textiles. They provide no direct benefit to human environments, though they act as scavengers of animal remains in nature.
