INSECTS INFESTING THE APPLE TREE.

The young caterpillars commence to feed on the new foliage, 

 and in four or five weeks they attain their full growth ; they 

 then descend to the ground, which they enter to a depth of 

 several inches ; here each caterpillar forms a small cell, in 

 which to pass the pupa stage. The A. vernata deposits her 

 eggs early in the Spring ; the caterpillars attain their growth 

 in four or five weeks, and then enter the ground to pass the 

 pupa state.
