lO A GUIDE FOR THE STUDY OF ANIMALS 



5. State how the fuzz and dust on your specimen might 

 influence a bird's liking for it. 



6. Contrast the size and usefulness of the wings of the 

 butterfly with those of some other insect you know about ; 

 contrast their legs ; state how development of one set of 

 structures may cause another set to be simple or feeble. 



7. Most moths are active by night. What explanation 

 can you give for their large eyes and expanded feelers .'' 

 Feelers of insects may be for any or all of the following : 

 touch, taste, smell, and hearing. 



Suggested drawings. 



a. The butterfly or moth. 



b. An antenna (feeler). 



THE LIVING CATERPILLAR 



Materials. 



Living caterpillars in cages or covered jars for individual 

 study, and other specimens in cages with foliage for food 

 or concealment. 



Observations. 



The pupil should observe the general form and external 

 construction of the caterpillar, watching it feeding, in 

 action, and at rest. 



Notice how the creature moves. Find its head, its 

 segments (similar divisions of the body), and its breathing 

 holes along the sides of the body. Try to find its eyes, 

 any feelers, wings or paddles. Try to loosen it from its 

 support ; find the tiny hooks on the feet for clinging fast. 



Questions. 



I. Give the general color of your specimen and explain 

 how this color may make it conspicuous or may aid its 

 concealment.
