Caddisfly larvae are aquatic, slender, with a segmented abdomen that is usually hidden within a portable protective case. Caddisflies that live on soft sediment often build wide, flattened cases that act like a snowshoe, keeping the insect from sinking. Larvae of some species move under the rocks, where they build solid shelters of sand and stones to protect the transforming pupae. Caddisfly larvae are known as hellgrammites for their ferocious appetites. Protein composition of silk filaments spun under water by caddisfly larvae. The net, which is stretched across the plant stems, stones, or arms constructed by the larvae, can be in the form of extension of the shelter or placed aside. They then emerge from the cocoon, float to the water's surface or the shore, and finish their transformation to an adult, terrestrial insect. Why not? Whether they are in a case or not, all caddisfly larvae are identifiable by their ability to create silk (which they use to make cases), the hardened skin on their head and on at least one thorax segment, three pairs of segmented legs, and lack of wing pads or visible antennae.

Larvae continuously clean their nets by picking off inorganic pieces and consuming organic matter. Prolegs are equipped with claws used to hold the larvae inside the retreat or on the substrate when crawling around. Molannidae (Hood casemaker caddisfly larvae) (Plus More Plant Help). . Larvae undulate their body to create a flow of oxygenated water through the case. Caddisflies undergo complete metamorphosis, meaning that their lifecycle is similar to that of a butterfly: they have a larval stage, a pupal stage during which metamorphosis occurs, and an adult stage that looks entirely different from the larval stage. A few weeks . Position and size of the plates are often important identification features among the species. The larvae are sensitive to pollution and thus serve as an indicator of water quality.
