Divided into 45 families,with some 12,000 species and 600 genera, the Trichoptera or caddisflies are one of the most diverse orders of aquatic insects. They are closely related to the Butterflies and Moths (Lepidoptera) with the Trichoptera having the more primitive characteristics. Some caddis flies can be confused with some species of moths, but the wings of the caddisfly is hairy not scaled as with moths. The name Trichoptera comes from the Greek trich, "hair" + ptera, "wings".
