NEUROPTEROID ORDERS 47 



The larvae are aquatic and are called Caddice-worms. 

 They live in running water and form cocoons of various 

 materials, twigs, sand, pebbles and silk, which they spin 

 as do caterpillars. These are often attached to the under 

 sides of stones. The larvae are caterpillar-like, but may be 

 recognized by their habitat and by the absence of the pro- 

 legs.
