The larvae of these interesting and often higly abundant insects are caddis-worms. They live in stream and lakes and employ a wide variation of building materials from which to construct the protective case or tube in which they live. The foundation is silk to which tiny stones, sticks, etc. are attached. Species found living in quiet waters may be reared in an aquarium and their habits observed.
