96 INSECTS INJURIOUS TO THE APPLE. 



the blossoms and newly-fornied fruit, thereby causing great 

 disappointment to fruit-growers, who have perhaps waited 

 patiently for years for the fruit of some new or interesting 

 variety, and have their hopes excited by seeing, it may be, a 

 single bunch of blossoms set well and appear promising, 

 when this mischief-maker commences its depredations on 

 the young fruit, drawing the several portions together with 

 threads of silk, and partly devouring them. It sometimes 

 contents itself with injuring the leaves only, drawing one 

 after another around its small inside case until there is 

 formed a little cluster of withered and blackened leaves. 

 Another of its tricks is to gnaw a hole into the top of the 

 branch from which a bunch of blossoms issues, and, tunnel- 

 ling it down th« centre, cause its death. 



These larvae are usually full grown by the middle of June, 

 when they change to dark-brown chrysal ids within their nests, 

 from which the perfect insects escape in July. 



The moth (Fig. 94) measures, when its wings are ex[)anded, 

 about half an inch across. It is of an ash-gray color. The 

 fore wings have a whitish-gray band across the middle, and 

 there are two small eye-like spots on each of them, one, near 

 the tip, composed of four little black marks on a light-brown 

 ground, the other, near the hind angle, formed by three 

 minute black spots arranged in a triangle, with sometimes 

 a black dot in the centre. The hind wings are dusky brown. 



The attacks of this insect are not restricted to the apple; 

 it is injurious also to the cherry and plum. Small and in- 

 significant as it appears, it is capable of much mischief. The 

 only remedy suggested is to pull off and crush the withered 

 clusters of leaves containing the caterpillars or chrysalids 

 early in the spring.
