CLASSIFICATION AND DESCRIPTION OF COMMON INSECTS 217 



Lesser Peach Borer {Synanthedon pictipes G. and R.)- — This native 

 insect occurs in most of the Northern States, in Ontario, and in some

 and the moth emerges in June and July. About a month earlier than 

 S. exitiosa. Attack by this insect usually follows mechanical and canker 

 injuries.
