What are bagworms known for?

Bagworms are known primarily for living in a silk "bag" for their entire lives. These fascinating pests, which are the larvae of a type of moth, create distinctive protective casings or bags from silk and plant material, such as leaves and twigs. This unique adaptation serves multiple purposes: it camouflages them from predators and provides protection as they feed and mature. As they grow, bagworms may enlarge these bags, continuing to incorporate plant materials around them.

While bagworms do have some associations with webs and may exhibit flight behavior, their defining characteristic is the silk bag in which they reside throughout their life cycle. This behavior is significant for understanding their biology and controlling their populations, especially in ornamental and landscape settings. The other options detail attributes related to behaviors or life stages of different insects but do not accurately capture the hallmark characteristic of bagworms.
