Insects are produced from eggs, which are hatched after 

 they are laid in some favorable place ; or, in some cases, 

 they are hatched in the body of the parent insect, and 

 then brought forth as moving forms. 



In passing from the egg state to the adult state, Insects 

 undergo great changes of form and habit. These changes 

 are called transformations or metamorphoses and they 

 are so great in most cases that the same insect at differ- 

 ent ages may easily be mistaken, by one not an entomolo- 

 gist, for as many different animals. There are at least 

 three more or less distinctly marked forms, or stages, or 

 states in the life of every insect after it leaves the egg 

 the Larva (Figs. 370, 371, 374), the Pupa or Chrysalis 

 (Figs. 365, 372, 375), and the Imago state (Figs. 373, 376). 



In the larva state Insects are more or less worm-like, 

 and consist of thirteen or more apparent segments, one of
