which are so nicely protected by the woolly cover that is of 

 a somewhat oily nature, thus preventing watery liquids 

 from adhering to the bodies of the insects or penetrating 

 the masses of eggs. 



The Browntail Moth (Euproctis chrysorrhea) . A moth 

 very similar in size to the Gypsy moth, but nearly white and 

 more destructive in that it feeds for about a month in the 

 fall and then again in the spring and early summer, and that 

 the female moth can fly a^great distance. The egg clusters, 

 which are laid on the under side of the leaves on the extreme 

 ends of the branches in August and September, are covered 

 with brown hairs much like those of the Gypsy moth. The 

 eggs soon hatch and the larvae feed for several weeks, when 

 they draw the edges of the leaves together, making a water- 

 proof nest in which they pass the winter, and from which they 

 come out in early May and feed on the young leaves of the 

 oak, apple, wild cherry and a few other trees. It is destroyed 

 by cutting and burning its " nests " during the winter, and by 

 spraying with arsenate of lead when the leaves begin to show 

 in the spring, or in the fall about the time the eggs begin to 

 hatch. 



The Gypsy Moth (Porthetria dispar). This pest is 

 becoming so widely distributed over New England and a 

 few other sections that, notwithstanding the fact that the 

 female moth can scarcely fly, it is one of our most destruc- 

 tive insect pests. It feeds upon most of our trees and 

 shrubs, on the lawn, in the garden and in the forests. The 

 work, which is almost pure white in color, lays its eggs in 

 the early fall in brown, hair-covered clusters of from 200 

 to 400 in crevices of the bark, on the under side of branches, 

 in stone walls, rail fences, sides of buildings or other secluded 

 places. These eggs hatch out in early summer, the larvae 

 feed voraciously for about a month, when they go into the 

 chrysalis state for about another month and then come
