 tigation, the rudiments of the future Fly may be 

 detected in the Caterpillar, provided it be ex- 

 amined but a very few hours before its trans- 

 formation into the chrysalis. 



It is in the larve or caterpillar state that most 

 insects are peculiarly voracious, as in many of the 

 common caterpillars of Moths and Butterflies. 

 In their complete state many insects are satisfied 

 with the .lightest and most delicate nutriment ; 

 some do not feed at all, while others, as several 

 Beetles, Dragon-Flies, &c. devour animal and 

 vegetable substances with a considerable degree 

 of avidity. 



Some insects undergo no change of shape, but 

 are hatched from the egg complete in all their 

 parts, and only cast their skin from time to time 

 during their growth, till at length they acquire 

 the full size of their respective species.
