Caddisflies are aquatic insects belonging to the order Trichoptera. They are commonly found in freshwater habitats like streams, rivers, and ponds. Caddisflies are known for their unique larvae, which often create protective cases from materials like twigs, stones, and plant fibers. These cases help shield them from predators and environmental factors. Adult caddisflies resemble moths and have two pairs of wings covered in fine hairs. They are typically active during the evening and are attracted to lights. Caddisflies play an important role in the ecosystem, serving as food for fish and other wildlife while also contributing to the breakdown of organic matter in aquatic environments.
