Their wings and back are vari- ously colored with red, yellow, and brown, while the body^ color is light yellowish-green. In May they begin to appear, and continue on the vines until the leaves fall. The adult hoppers spend the winter in masses of rubbish or leaves ac- cumulated against fences or other obstruction, where thou- sands of them may be seen on warm winter days. The eggs are thrust under the skin of the lower side of the leaves of the vine in June. The nymphs (Fig. 267 d and e) live on the under sides of the leaves and suck out the substance of the i-^af. As the nymphs grow they shed their skins four times,.
