The eggs are laid in July. The caterpillars hibernate through 

 the winter and complete their growth in the spring. 



There are several species of climbing cut-worms that do a 

 great deal of damage. They climb the trees in the night and 

 cut off the buds. 



INFESTING THE LEAVES. 



There are several species of very small moths whose larvae 

 feed on the leaves and buds of the apple. The most common 

 of these are the following. 



Apple-leaf Bucculatrix, Bucculatrix pomifoliella. This is a 

 very common insect in some sections of the State. The larvae 

 have no protection like the leaf rollers, but feed on the leaves 

 and have the power of spinning the fine threads the same as the 

 others, but these are for letting themselves to the ground. As 

 soon as they reach maturity they spin little silken cocoons and 

 attach them to the small twigs. 



These cocoons remain on the tree through the winter and 

 may be killed with the whale oil soap solution. I have seen 

 them in abundance in some orchards. Specimens have been 

 sent into the office for identification. 



There are several species called leaf rollers, which do a great 

 deal of damage. 



The banded leaf roller, Archips rosceana, is perhaps the most 

 common. All these tiny caterpillars have the power of secreting 

 silken threads with which they sew up the leaves. This species 

 draw the young leaves around the blossom bud cluster and feed 

 within this enclosure similar to the preceding species. The 

 caterpillars are very active when disturbed and often wriggle out 

 and drop to the ground. They vary in color from a greenish 

 yellow to shades of brown. The larvae do up and change to the 

 pupa and hatch out into a light brown moth with darker bands 

 across the wings. 



The leaf roller, Ancyhs nubeciilana, is another common 

 species. The young caterpillars do not appear until about the 

 first of July. They sew up the edges of the leaves with silk 

 threads ; this is their house in which they feed. When the 

 leaves fall these caterpillars remain in them through the winter 

 and the moth hatches out in the spring ready to lay her eggs.
