Tinea pellionella (Case-bearing clothes moth larva fragment)

Indoor environments, particularly in closets, drawers, or storage areas where natural fibers are present.

Keratin-rich materials including wool, silk, feathers, fur, hair, and carpet fibers.

The larva builds a portable silken case incorporating fibers from the material it is eating. It drags this case along as it feeds and eventually pupates inside it.

Poses a significant risk to household textiles, clothing, and upholstery. It is considered a domestic pest with no direct benefits to humans in an indoor ecosystem.
