About Caddisflies
Trichoptera (caddisflies) includes ~14,500 described species worldwide. Larvae are aquatic and build protective cases from silk, sand, pebbles, and plant material - each species creates a distinctive case design.
Economic Impact
Caddisfly larvae are among the most important biological indicators of water quality. Their presence or absence in streams is used by the EPA and state agencies to assess pollution levels and ecosystem health.
Ecological Role
Caddisfly larvae are critical food sources for trout and other freshwater fish, making them essential to recreational fishing industries worth billions annually. Their silk is being researched as an underwater adhesive for medical applications.
