Natural Habitat

Indoor environments, particularly in warm, humid regions, found on walls, ceilings, under furniture, and in closets.

Diet & Feeding

Feeds on spider webs, hair, feathers, wool, dead insects, and occasionally synthetic fibers.

Behavior Patterns

The larva constructs a portable, flattened, silk case resembling a melon seed, dragging it along surfaces as it moves. It pupates inside the case and eventually emerges as a small moth.

Risks & Benefits

Risks include minor damage to natural fiber fabrics, carpets, and stored woolens. They pose no health threat to humans and act as occasional scavengers of household debris.
