About Caddisflies: the wider group
Order-level background for Trichoptera, the group containing Smicridea dispar. Species-specific details appear above.
Group overview
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.
Ecological role of the group
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.
Economic and practical significance of the group
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.
Recorded sources for this group: EPA, freshwater ecology research. Imported estimates may describe particular regions or reporting periods.
