The young leaves and fruit of or- 
tree Leaf-roller. Original. chard trees and bush fruits are at- 
tacked by yellowish larve, which spin 
threads wherever they go, drawing leaves somewhat together. The 
full-grown worm is about an inch long, has 
a black head, and has a few short hairs 
scattered over its body. It is active when 
disturbed. 
The pest appears very early in spring, 
when the buds are first unfolding. It hatches 
from eggs laid in flat masses on the bark. 
There is one generation annually. 
Early spraying with arsenate of lead or 
Paris green at the time that the buds are 
opening, and again when the blossoms have 
fallen, is the means of control.
