hopper family. Its form 

 does not change materi- 

 ally from the time it is 

 hatched until it is full 

 sized. Thus the grass- 

 hoppers become adult 

 by a growing process 

 termed incomplete meta- 

 morphosis, showing no 

 marked change in form 

 (Figure 10). 



10. Complete Metamor- 

 phosis. — Certain other 

 insects, for example the 

 codling moth, hatch into 

 caterpillars from the 

 eggs that the female lays 

 in the apple. These 

 caterpillars are known 

 as larvae (dar've : Latin, 

 larva, mask). The larvae 

 of the codling moth are 



the " worms in the apple." These larvae are not recog- 

 nized from their external appearance as young codling
