What insect or fly uses a paper tube like covering for its young?

The insect that uses a paper tube-like covering for its young is the caddisfly. Caddisfly larvae create protective cases from materials they find in their environment, such as twigs, leaves, and small stones, which they use to shield themselves from predators and harsh conditions. These cases resemble tubes and are essential for their survival during the larval stage. Upon maturing, caddisflies emerge as winged adults, completing their life cycle.
