CHAPTER X. 

 FIELD WORK ON LEPIDOPTERA. 



An expedition for lepidopters should be made to the 

 open meadows and fields some sunshiny afternoon, 

 between two and four o'clock. 

 Discover : 



What colors are represented in the lepidopters which 

 you find in these places? 



What are they seeking as food ? 



Are their habits of visiting flowers promiscuous, or 

 constant as to a given food source ? 



Do they know an enemy when one approaches them ? 



Can you tell anything about how far a butterfly 

 can see? 



Are you able to see the synchronous wing action? 



What is the manner of disposing of the wings when 

 not in use, that is, when the insect is resting on some 

 object? 



Do butterflies and moths ever walk? 



Do they see or smell their food? 



Another expedition should be made early in the day, 

 before the dew is off the grass, to some waste lot or the 

 south side of hedge rows, or wherever the grass grows tall. 



Can you discover whether butterflies sleep ? 



Are flowers fragrant at this time of day? 



Is the dew on the insects as well as on the flowers? 

 An expedition should be made to the woods early in the 

 afternoon.
