Plaster Bagworm larvae are known to feed primarily on what?

• A. Wool and textile fibers
• B. Spider webs
• C. Wood fibers
• D. Paper products

Answer: (B)

This item tests what plaster bagworm larvae primarily feed on in indoor environments. Plaster bagworm larvae are scavengers that specialize in consuming protein-rich spider webs, often found in corners and along ceilings where webs accumulate. They also ingest dust and debris trapped in those webs, which supports their diet. While they may occasionally nibble at wool or fabric fibers, their main staple is spider webs, making that option the best fit. They are not wood feeders, and paper products are not their primary food source, unlike some other household pests.
