Cloth Moth Larva (Casemaking)

Indoor environments, specifically dark areas with access to animal-based fibers like wool, silk, or fur.

Keratin-based materials including wool rugs, sweaters, feathers, and organic debris.

The larva constructs a protective silken case incorporating fibers from its food source, dragging it along as it feeds and eventually pupating within it.

A significant household pest that causes physical damage to clothing and textiles; essentially zero benefit to human-made environments.
