In this inactive condition the insect remains for three or four weeks, sometimes longer, when the moth appears. The moth (Fig. 98) is a very pretty object. Its fore wings are ash-gray, whitish towards the outer margin, and crossed ^ Q^ by three irregular black lines, which are faint or indistinct towards the inner edge; near the middle of the wing there is often a round, whitish spot, with a black dot in the middle. The hind wings are dull-whitish, dusky towards the tips. Beneath, both wings are of a silvery-whitish hue, sprinkled with blackish dots towards the outer edges. When the wings are expanded, they measure from three-quarters of an inch to an inch or more across. The first moths appear early in spring, and attach their eggs to the young foliage; the second brood appear in July. These attach their eggs to the leaves, and produce larvae in August and September, which, when their growth is com- pleted, change to chrysalids within the folded leaves, as already described, and are carried to the ground with the fall of the leaves in autumn, where they pass the winter in the pupa state and produce moths in the following spring. These larvae feed also on cherry, peach, elm, poplar, and other trees. They are seldom sufficiently numerous to be troublesome, but if at any time a remedy is required they may be destroyed by syringing the leaves with Paris-green or hellebore mixed with water, as recommended for No. 35. When the trees on which they are feeding are suddenly jarred, the larvae will drop to the ground, and by takin^i advantage of this peculiarity they may be captured and destroyed.
