skilful from experience. The sides of the larger leaf . . . are drawn 

 together by silken threads, so that the edges of the leaf meet closely and 

 form a light and commodious cavity, which securely shelters and com- 

 pletely conceals the included caterpillar. This in time is eaten like the 

 first, and another is formed in like manner. At length the caterpillar, 

 having eaten up and constructed several dwellings in succession, and 

 changed its skin three or four times, comes to its full size, leaves off eat- 

 ing, and seeks a suitable place in which to undergo its transformations" (Sec. 

 " The butterflies from the first brood appear in July, and from the second 

 in September " (in Mass.) 



Mr. Scudder's account is very brief, Butterflies, p. no : " The cater- 

 pillar constructs a somewhat similar though more perfect nest (i. e., than 

 what is called a Tiger Swallow-tail, — whatever that may be, some Asiatic 

 species we may suppose), by fastening together the opposite edges of a 

 nettle-leaf, the tip of which it eats 7vhen too lazy to go from home, until 

 there is barely enough lef: for shelter ; its weight causes the leaf to droop, so 

 that the nest is easily discovered." 



The only information contained in Westwood & Humphrey's British 

 Butterflies, 1848, on the habits of the larva oi Atalanta is this : According 

 to Sepp., the caterpillar, after it is hatched, selects a Nettle-leaf, which 

 it draws together with threads into a roundish, hollow form, leaving for the 

 most part an opening into the interior both before and behind, thus serving 

 both for shelter and food until almost devoured, when it selects a fresh 

 leaf, and proceeds with it in the same manner, one caterpillar only being 

 found on a single leaf, thus indicating a peculiar liking for a solitary life." 



Boisduval and Leconte, 1833, say : " It lives isolated on Nettle, and 

 is almost constantly concealed between many leaves drawn together by 

 some threads."
