10 METAMORPHOSIS. 



Larva, pupa aud imago, 

 That are commou to all insects ; 

 Let us now regard the pupa 

 In its various forms and phases. 



Sometimes it is hard and lumplike, 

 Wrapped in coating tough and leathery ; 

 It moves not, and of course it eats not ; 

 'Tis to aU appearance lifeless : 

 Such a pupa is amorphous. 

 Shapeless, and we call Amorpha 

 All the insects with such pupae. 

 Now, if these amorphous pupae 

 Come to butterflies and night moths, 

 With four wings so broad and ample. 

 Thickly covered up and hidden, 

 With small scales of different colours, 

 Scales that seem almost like powder. 

 When rubbed off upon the finger. 

 Then we call the insects Scale Wings, 

 Lepidoptera or Scale Wings ; 

 But if they have two wings only, 

 And those two are quite transparent, 

 Without any scales or clothing, 

 Then we call such insects Two Wings, 

 DiPTERA, or having two wings. 



Let us take another pupa ; 

 Aud this also moves not, feeds not, 

 But its limbs are quite apparent,
