Life History. — The eggs 

 are deposited in the spring of 

 the year upon various fruit 

 trees, wild trees and bushes. 

 The young attack the foliage, 

 almost entirely defoliating 

 the plants. When full grown 

 the larvae seek the ground 

 where they pupate and thus 

 pass the winter, emerging 

 early in the spring as adults. 

 These are often seen flying during the day.
