Plaster Bagworm (Case-bearing Moth Larva)

Typically found indoors in high-humidity environments, often seen crawling on walls, ceilings, and floors.

Feeds on spiderwebs, wool, hair, silk, and other natural detritus/fibers.

The larva constructs an oval, silk-lined case covered in sand and debris. It can emerge from either end of the case to feed or move, eventually pupating inside the case to become a small gray moth.

Generally harmless to humans but considered a minor household pest as it can damage natural fabrics (wool, silk) and create unsightly cases on walls.
