The insect passes the winter in the caterpillar state, hiber- nating in some secure retreat until aroused to activity by the warmth of spring, when, after feeding a few days on the young vine leaves, it becomes a chrysalis, producing the moth about ten days afterwards. The moths within a few days deposit their eggs on the leaves of the vine, which hatch early in June, and the larvae nearly complete their growth by the end of the month, pass into the chrysalis state, and appear as moths again in July and August. These latter deposit eggs for the second brood of larvae, which, before reaching maturity^ become torpid, and remain in this condition until spring. The moth (Fig. 279) measures, when its wings are ex- panded, about an inch and a half across. Its color is pale ochre-yellow, crossed by many grayish-brown lines, and clouded with patches of the same, par- ticularly along the margin of the wings. The body and legs are similar in color to the wings, the latter being marked with black about the joints. Early in June the reddish geometric caterpillars of this moth are found upon the leaves^ out of which they eat numerous pieces of various sizes and shapes. By the middle of the month they become full Fig. Please note that these images are extracted f
