HOW TO KNOW THE BUTTERFLIES 



ing near one particular spot all its life. It may 

 be found near swampy places from the middle of 

 June until the middle of July, in Ontario and the 

 northern half of the United States. 



The habits of the caterpillars are most eccentric. 

 They live together in a common nest made by 

 weaving together the leaves of their food-plant and 

 portions of the surrounding herbage. After the 

 third molt they cease feeding and remain thus 

 in their tent until the next spring. They do not 

 fall into a lethargy and so endure hunger in a 

 trance. They simply cuddle down and volun- 

 tarily fast in the presence of plenty. We kept 

 a brood in a box once during their fast-period. 

 Every time we opened the box inquiring black 

 heads would be lifted in an impatient manner 

 that said quite plainly " Let us alone, please." 

 There they waited from midsummer until the 

 snakehead had put forth leaves next spring. 

 They resumed eating as calmly as if a fast of nine 

 months were no trick at all.
