Trichoptera(redirected from caddis fly)
Also found in: Dictionary, Thesaurus, Encyclopedia.
An order of insects in which the aquatic larvae (caddis flies) construct a protective case (caddis) of bits of submerged material in a highly specific form; commonly found attached under stones in freshwater streams. The adult caddis flies, having hairy wings, shed their hairs and epithelia, causing hay fever-like (allergic) symptoms in sensitive people.
[tricho- + G. pteron, wing]
