A caddisfly is a small, moth-like insect with a slender body and long antennae, often found near freshwater habitats. It gets its name from the protective case, made of materials like plant fragments or small stones, that it constructs during its larval stage. The caddisfly larvae are aquatic and use their cases as a means of camouflage and protection. Once they reach adulthood, caddisflies have short lifespans and are primarily active during the evening. They are important indicators of water quality and play a crucial role in aquatic ecosystems as both prey and predators.
