The beautiful little species Urythroneura vitis (Fig. 264) is very destructive Fig. Erythronkura VXTI8, Harris,—magnified. to vine leaves. In winter they shelter themselves under fallen leaves and in litter, and come forth in spring to deposit their eggs on the leaves, the juices of which they suck, both in the wingless larval state and in that of the mature insect. In this group are also placed the troublesome Aphidoe or Plant-lice, and the Coccidoc or scale-insects of our fruit trees. In these groups the females are wingless. 7' IVeuroptera. Among the most common insects of this order are the Uphef/ieridaey "May-flies" or " Shad- flies ;" the larvae of which live in water, and in summer emerge in countless swarms on our lakes and rivers, to fly for a few hours or days, and deposit the eggs of a new brood in the water.
