Life History. — The life history is practically the same as that of 

 the spring cankerworm, but the eggs are deposited in a compact mass 

 and glued to the twigs and covered with hairs from the female's body 

 in the late fall or during the milder portions of winter, as late as 

 March. The young hatch about the same time as those of the spring 

 forms and work about the same. The adults issue from October to 

 December, or as late as spring, and immediately crawl up the trunks 

 to deposit their eggs.

 cherry. (After Craw.) 



Distribution. — Found in the central and northern parts of the State. 

 Food Plants. — The foliage of the apple, prune, cherry, apricot and 

 other fruit trees are attacked. 



Control. — Control measures as adopted for the spring cankerworm 

 may be used for this. Bands around the tree trunks will not prove as 

 effectual, because of heavy winter rains, unless they are occasionally 

 renewed. These barriers must be put in place during September and 

 October and continued until spring. 



Natural Enemies. — The species is subject to the same natural enemies 

 as is the preceding insect.
