Caddisflies are perhaps the most underappreciated aquatic insect family. To many non-anglers, they look like little moths. Adults have wings shaped like a tent, segmented bodies without tails, and antennae that give a moth-like appearance. But unlike moths, caddisflies spend most of their lives living in the water as larvae, which look like little worms. Most, but not all, caddisfly larvae live in some type of case that they build from rocks, sand, plant material, or even their own silk.
