The caddis fly is a small aquatic insect that forms a vital part of the food chain in freshwater ecosystems. Other synonyms for this insect include sedge fly, rail fly, and moth fly. The name "caddis fly" is derived from the protective casing made of silk, gravel, and plant material that the larvae create, which somewhat resembles the coarse woolen cloth called "caddis." Caddis flies are important indicators of the health of freshwater habitats, and the species are used in bioassessment programs to monitor water quality. With their lifespan of a few days at most, caddis flies are a short-lived yet critical component of freshwater ecosystems.
