278 BUTTERFLIES 



the common garden pest of the genus Chenopodium. The 

 eggs are laid singly, generally on the upper surface, and 

 hatch in about five days into tiny caterpillars that make a 

 little shelter for themselves by cutting out the edge of a 

 leaf and folding over the blade, sewing it in place by a few 

 silken threads. Here they remain and feed upon the green 

 pulp of the succulent leaves either within the nest or 

 near by outside. They remain in these cases until the 

 time for the first moult, when they are likely to line the in- 

 side of the silken web before moulting. After this they 

 make new cases for concealment and shelter, the cases as 

 they grow older being generally made of two or more 

 leaves securely bound together by silken web along their 

 margin. When they become full grown, they spin a silken 

 cocoon and change to yellowish green chrysalids from 

 which the butterflies emerge a little more than a week later. 

 This species is supposed to be double-brooded in the 

 north. The full-grown caterpillars of the second brood 

 sew up their leafy cases very carefully, making them of 

 such thick silken webbing that they are watertight. 

 They remain in these coverings until the following spring, 

 when each changes, still within the case, into a chrysalis 

 from which the butterfly comes forth in April or May. 



THE TRIBE OF THE SMALLER SKIPPERS 



In the members of this tribe the tip beyond the club 

 of the antenna is short and the abdomen is long enough to 

 extend as far as or farther than the hind wings. The 

 caterpillars have long and slender bodies with the upper 

 part of the head, when looked at from in front, tapering
