 habits.

The growing berries are eaten into and the contents devoured by a 

 small, greenish caterpillar, half an inch long when full grown. The work 



begins when the berries are small, and con-

 by a small hole, usually thus destroying 

 three or four by the time it is full grown.

 of berries together. When disturbed, they promptly let themselves 

 down by a silk thread. There is one generation annually. Hiber- 

 nation takes place on the ground in the pupal stage.
