Fam. VII. Phryganeidse.— -Caddis-flies. 

 Tbe wings are more or less clotbed with hair ; the bind ones are 

 larger than the front which are held in a roof-shaped manner over the 

 body when at rest. Antennae are thread-like, mandibles are absent. 

 The metamorphosis is nearly complete. The larvee are caterpillar-like, 

 usually inhabiting cases of their own construction. The pupa resem- 

 bles the perfect insect.

These insects have the appearance of small black moths (Lepidoptera) 

 and are to be found in the neighbourhood of water, in which the larval 

 stage is passed. Fig. 32 shows an adult caddis-fly. They are unim- 

 portant. 



Useful Neuroptera. 

 The Order cannot be said to contain many insects of use to man. 

 The dragon fly, in its adult condition, and the ant-lion larva are both 

 carnivorous and prey upon insects and both probably do a certain 

 amount of good by catching and feeding upon noxious insect pests. It 

 is not improbable, however, that they also in this way kill off useful 

 insects. The dragon-fly catches its prey entirely upon the wing.
