has a wing expanse of 3-5 of an inch. They Hve 2 or 3 weeks, 

 during- which time they mate and the eggs are laid. The eggs, 

 which resemble small fish scales, are laid singly or in clusters, 

 mostly at night, on the under side of the leaves. The eggs 

 hatch in 7 to 10 days. The young larvae feed upon the epider- 

 mis of the leaf, forming a silken tube for protection. After 

 the fourth moult, which occurs the last of August or the first of 

 September, or before the leaves fall, they leave the silken tubes 

 and form a silken winter home (hibernaculum) on the smaller 

 twigs, near the buds, in which they spend the winter. The 

 appearance of the hibernating larva in the spring completes the 

 cycle of life. 



REMEDIES. 



Pull off and burn the withered clusters of leaves containing 

 the caterpillars and chrysalids early in spring. Spray with 

 arsenate of lead (Formula 6) as soon as the buds begin to 

 swell in the spring. It will not do to wait until the attack is 

 made. 



4. Leaf Sewer. 



(Ancylis nubcculaiia.) 



The leaf is folded along the mid rib, the two sides being 

 brought together, the caterpillar constructing its nest within 

 (fig. 22). The winter is passed in the larval condition in the 

 folded leaves which lie on the ground. In April the larvae 

 transform in pupae and about 10 days later the moths begin to 

 appear, laying eggs in June. The caterpillar is about 3^ inch 

 in length when full grown, yellowish green, with yellow head,
