here, after remaining at rest for some minutes, 

 to permit the superfluous moisture to evaporate, 

 it throws off its covering, and soon takes w^ing 

 in search of a mate. Many species of a smaller 

 size proceed in a different manner; the nymph 

 ascends to the surface of the w^ater, w^here it is 

 emancipated from its exuvia, vs^hich serves as a 

 boat to support the perfected insect, until its 

 vrings are sufficiently developed, dried, and pre- 

 pared for flight. 



The w^ord Phryganea is derived from ^p^v-vov, 

 a bundle or fagot of sticks.
