c) No metamorphosis or Ametabola. — The insect of this type of 

 metamorphosis have no distinct external 

 changes in development, except in size. 

 When the young hatches from the egg it 

 resembles its parents and scarcely shows 

 any changes in appearance during the 

 course of development. This is especially 

 true of a small number of wingless insects 

 belonging to the orders Protura, Thysan- 

 ura and Collembola. 



These insects shed their outer coat (molt) 

 from time to time to permit more comfort- 

 able growth, but all of these successive 

 stages appear very much the same except 

 in size. Some would call these immature 

 stages "nymphs" but "young" seems to be 

 a more accurate and preferred term.
