HOW TO KNOW THE BUTTERFLIES 



of the butterfly are graphically described thus by 

 Dr. Wittfield. " Palamedes roosts on the highest 

 tree it can find, oak or palmetto. I have seen 

 four to six near sundown fluttering about the 

 tree where they finally settle and remain. Some- 

 times three or four rest on one palmetto leaf with 

 spread wings." 



The caterpillar behaves very much like that of 

 troilus, folding the leaf together and holding it 

 there with silken threads crossed, and hiding 

 within. However, it differs from troilus in this 

 respect, that it eats the leaf of which the nest is 

 made until it is too small for protection and then 

 it moves on to another leaf. This species is con- 

 fined to the southern half of the United States, 

 east of the Mississippi. In the more southern 

 part of its range there are at least three broods 

 annually ; and the winter is passed by both larvae 

 and chrysalids.
