Tliey feed on the upper surface of the leaves, eating only the upper epidermis, and leaving the lower intact (fig. 74). When very numerous the leaves turn brown, die, and fall off in the summer, and a fresh lot of foliage takes its place, thus weakening the trees. We have seen young trees killed outright by them. The adult SawHy (fig. 73) is a small glossy black insect, about one- fourth of an inch in length; the wings are iridescent, with the middle area smoljy black, and are about three - quarters of an inch from tip to tip. The parent ily comes out of the ground beneath the in the spring, generally in April.
