You will have noticed in brooks and outlets, more particularly towards spring, several kinds of a creature called «  the strawbait », or «  caddis worm, «  small creeping things encased in a kind of husk formed of bits of straws, small shellls, and grit, and glued as it were together,which coats the insect’s body with a mail of consederable strength. These insects have commonly ben supposed to be the larvae of the Mayfly, but further research has shown that they are in reality those of caddis-flies, which entomologists call Phryganidae.
