6 NATURE STUDY. 



found to have a small, irregular opening, which, in all 

 probability, accounted for the unexpected visitor. 



Caterpillar Number Three was given away just as it was 

 about to enter the chrysalis stage. Number Four lingered 

 until Oct. 30, having made no perceptible growth, and 

 with very little change in color, for many daj's. 



Although all leaves disappeared from the bush on which 

 the larvae were found, some others were obtained in shel- 

 tered places and furnished up to the time of the death of 

 Number Four ; but if the season at their birthplace was 

 ended, it is quite likely that other conditions were unfavor- 

 able to their existence. 



No attempt at concealment was made by the caterpillars 

 at any time, but in one instance a webw^as spun which re- 

 sulted in a mat wdiich was slightly smaller than the leaf 

 surface to which it was attached, thus making a sort of 

 spring bed, but the leaf edges were not drawn together. 



On June 2, 1903, came the climax in this life hi.story, 

 for, noticing that the chrysalis was becoming a dark color, 

 the first change since Oct. 8, I removed it from its venti- 

 lated glass-fronted box to a place where closer observations 

 might be made. 



Much to my surprise, within half an hour, I saw, where 

 my chrysalis had hung, a little black bunch of loose ends, 

 like bits of silk. A second glance proved the suspicion 

 that a butterfly had arrived. For perhaps fifteen minutes 

 it remained on the chrysalis, or on the leaf stem to which 

 it was attached, then it removed to an adjoining leaf, and 

 within half an hour the wings were fully expanded ; but it 

 was fully two hours later when the big black beauty used 

 them to fly to the open but screened window. 



As the caterpillar masquerades in the guise of a danger- 

 ous individual, so,- later in life, the insect passes, uncon- 

 sciously, perhaps, under the different names of Papilio
