Natural Habitat

Commonly found in humid, tropical, or subtropical environments inside houses, garages, or on walls.

Diet & Feeding

Larvae feed on fibers such as wool, silk, hair, and biological debris like spider webs or discarded insect parts.

Behavior Patterns

The caterpillar constructs a silk-lined, spindle-shaped case covered in sand or dust for camouflage. It remains inside the case, dragging it along as it feeds, and can emerge from either end to change direction.
