This insect, [fig. 15], is usually of a uniform rusty brown color. Four humps or tubercles are easily seen, two on each wing cover near the rear. The snout varies from half to the full length of the insect. With this snout it drills round holes into the apple; these holes are made for food, and are about one-tenth of an inch deep, widened out below like a gourd. The female deposits an egg in such hole, which soon hatches into a tiny worm that usually burrows to the core, and produces a reddish excrement. In a month, when fully grown, the worm is soft and white, without feet, wrinkled, and curved crosswise, as in b, [fig. 16]; too humped and crooked to crawl about out of the apple, it stays in and changes to pupa, as in a, [fig. 16], leaving the apple as a perfect beetle after two or three weeks. It passes the winter in the adult state and begins laying eggs about June 1, continuing until late in August. President Wellhouse says he has surely reduced them by spraying.
LEAF-CRUMPLER, OR LEAF-ROLLER.
The parent of this is a small grayish moth, d, [fig. 17], which emerges from the unsightly mass of dry leaves, as in b, [fig. 18], formed the previous season by the insect, and may be seen, gathered, and burned, during the winter. The female immediately begins laying eggs upon the leaves of the tree. During the fore part of June small, brownish worms appear, which at once construct tubular silken cases, in which they hide. They leave these cases, generally at night, to feed. As they grow they attach webs to the partly eaten leaves and gather them about themselves, so that finally the irregular mass of leaves completely hides the tubular case. In the spring, as the buds swell and the leaves appear, they come out and do great damage. They grow until in May, when they close up the opening to the case, and in two weeks the moth emerges, as above.
