Stages in the Life Cycle of the Stonefly Stages in the Life Cycle of the Caddisfly Unique & Interesting Characteristics of the Stonefly Unique & Interesting Characteristics of the Caddisfly • Caddisflies spend most of their lives as larvae, up to 2 years in some species. • Larvae look like caterpillars covered in a tube-like case of leaves, sand, twigs, or bark. Some can get to be about the size of your pinky when they are mature. • In the pupal stage the caterpillar is busy changing into a fly. This stage takes about two weeks. • Two weeks later the Caddisfly comes out of the pupa as a full grown Caddisfly. • The adult Caddisfly only lives about a month. • Stonefly eggs are covered by a sticky jello- like substance which helps the eggs stick to rocks or the bottom of the river. • For most species of Stonefly the eggs begin to develop immediately and take only three to four week to hatch. • Because Stoneflies need healthy streams to survive they are known as a clean-water insects. • When the larvae emerge as adults they are weak fliers and can be found resting on the shore of stream. • Adults can be identified by their brown and gray bodies and their delicate antennas. • Caddisflies are butterfly-like insects with soft, hairy wings. • The scientific name is Trichospteron. Trichos means “hair” and “pteron” means wing—hairy wing! • The wings touch at the top and look like the roof of a house. • Adults are lazy in the morning. They are more active in the evening and at night. • Caddisflies are best known for cases they make and live in. They also spin nets to have a safe place to live in.
