Comments: Caddisfly larva are aquatic. They build a protective case of silk around themselves, incorporating debris for camouflage and protection. Their presence is indicative of good water quality. Adult caddis flies emerge en masse for just a few weeks. After emergence, they do not eat, but they mate and the females lay eggs. Caddisflies are a preferred food of trout.
