Which pest's larvae are known for building webs within infested food material?

The Indian meal moth is recognized for its larvae that construct distinctive webs within infested food products. This behavior is particularly evident in pantry items such as grains, flour, and dried fruits, where the larvae create silk threads that can be seen as webbing. These webs can entangle food particles, making them difficult to spot and leading to contamination of the affected items.

The Indian meal moth's ability to infest stored products is a significant concern for food safety, as the presence of webs not only affects the quality of the food but can also render it inedible. This characteristic is a key identifier for pest control professionals dealing with infestations in kitchens and food storage areas, emphasizing the moth's role as a pest in stored food environments.

While other pests listed may have larvae with detrimental effects, they do not exhibit the same web-building behavior within food materials as the Indian meal moth does.
