All caddisflies use materials gathered in their immediate environments, and some species are less choosy than others. Larvae are sensitive to pollution and for this reason are used worldwide as the indicators of water quality. Most creep along rocks and other submerged objects in the clean waters of streams, rivers, and springs, where the movement of the water increases the oxygen level. Caddisflies are important members of the food web because they eat dead organic matter that has fallen onto or been washed into their habitat, and in some cases, help transport it to other habitats by carrying it along with silk threads spun from glandular hairs on their legs. Green (Caterpillar Like) Worm Found in Aquarium. Caddisfly larvae go through a number of molts before entering the pupal, or cocoon, stage. When that stage is nearly complete, usually in fall, they cut open the case, swim to the surface, undergo the final molt, and begin flying. Six caddisflies are listed as Missouri Species of Conservation Concern and thus are vulnerable to extirpation from the state. Case-building caddisflies are more commonly found in cleaner streams. Their larvae are aquatic and build portable, protective cases out of local materials, including grains of sand, bits of leaves and twigs, and other debris. Bio-Inspired Muco-Adhesive Polymers for Drug Delivery Applications. When fully grown, caddisflies leave water as adults by crawling out onto vegetation along the water's edge. Habitat: Habitat and Food Source (s): Adults do not feed and have vestigial mouth parts; larval stages have chewing mouthparts. These cases can be made of organic material, such as vegetation or debris, or small stones or sand grains bound together by silk the .

Caddisflies that build cases out of organic matter are found in slow parts of flowing waters and shallow areas of lakes and ponds where debris can accumulate, and where the neutrally buoyant case won't be swept away. The constructions are spliced together and glued down to the substrate by a silken thread. A caddisfly larva eventually pupates, sealing off the tube as it develops into an adult fly and then hatches. 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.
