See this bug in the Encyclopedia

Natural Habitat

Honey bee colonies, wax-related storage areas, and abandoned hives; they thrive in warm, dark environments where beeswax is present.

Diet & Feeding

Honey, pollen, and mainly beeswax (cerophagy). They are one of the few organisms capable of digesting plastic (polyethylene).

Behavior Patterns

They are nocturnal moths. As larvae, they tunnel through honeycomb, lining the tunnels with silk, which can entangle bee larvae and damage the hive structure.

Risks & Benefits

Risks: Major pest to apiculture (beekeeping) as they can destroy hive frames and weaken bee colonies. Benefits: Valuable for research in toxicology and plastic biodegradation; also used as a live food source for reptiles and birds (waxworms).
