INSECTS INJURIOUS TO THE APPLE. 



down from the trees by a silken thread, they burrow into the 

 ground, forming a little oblong cell, five or six inches below 

 the surface, within which the change to a chrysalis takes 

 place, and from which the moth usually comes out late in 



October or early in November, but occasionally this latter 

 change does not take place until spring. 



The male moths have large and delicate wings (see Fig. 

 108) and feathered antenna. The fore wings, which measure, 

 when expanded, about an inch and a half across, are of a 

 rusty-buff color, sprinkled with brownish dots, and with two 

 transverse wavy brown lines, the inner one often indistinct, 

 while between the bands and near the edge of the wing there 

 is generally a brown dot. The hind wings are paler, with a 

 small brownish dot in the middle ; the body is similar in color 

 to the fore wings.
