The early broods of worms develop on dry bogs, or on the upland, 

 or on flowed bogs where some of the vines are not covered by winter 

 flowage. They are likely to go unnoticed, and steps to combat them 

 are seldom taken until 

 the berry feeding and 

 extensive webbing of 

 the later broods is be- 

 gun. The last brood is 

 slower of development 

 and will be found in- 

 festing fruit to a con- 

 siderable extent in Sep- 

 tember and October.
