Limnephilidae (Case-building caddisfly larvae) Caddisflies that live on soft sediment often build wide, flattened cases that act like a snowshoe, keeping the insect from sinking. Caddisflies undergo complete metamorphosis, meaning that their lifecycle is similar to that of a butterfly: they have a larval stage, a pupal stage during which metamorphosis occurs, and an adult stage that looks entirely different from the larval stage. These species may have been the inspiration for the caddisfly name. Caddisflies spend their entire larval development underwater feeding on small particles they can filter from water or pick off a rock. Careers.

Adult Caddisflies are mothlike insects, and the larvae are aquatic shelter builders. They breathe dissolved oxygen by diffusion across their soft tissues, and they have a limited ability to cope with low dissolved oxygen by wiggling their bodies within their cases. Fish keeping folks provide online guides and tips on what you need to know about keeping fish, caring for them, aquarium types, filters, and lots more.
