THE BUTTERFLY 31 



(a) Its manner of flight. 



(b) The kind of food, and the manner of feeding. 



(c) The natural enemies of the butterfly. 



(d) The position of the wings when at rest. 



8. What is the damage done by the cabbage but- 

 terfly ? 



It should be remembered that the common toad is 

 the best friend we have in the garden to rid the cabbage 

 of this pest. 



9. What is the life-history of the butterfly? This 

 question will be asked in connection with all the insects 

 we shall study ; 



therefore a gen- 

 eral answer should 

 probably be given 

 to make this point 

 clear. The cab- 

 bage butterfly lays 



its eggs usually on

 the lower surface 



of cabbage leaves. They are small and are pale-yellowish 

 in color. These hatch into larva, the so-called cabbage 

 worms. After the worms have fed upon the cabbage leaves 

 for some time, they spin from their mouths a silken pod 

 around themselves ; this pod is called the pupa. The pupa 

 is usually found on old fences or posts. In a short time the 

 pupa ruptures, and a full-grown cabbage butterfly crawls 

 out, dries its wings and flies away to begin the life history 

 of a new generation.
