I Sr~ F-519950 F-501808 Figure 80.—Adult of the poplar- Figure 81.—Galls in pine produced and-willow borer, Cryptorhyn- by the pine gall weevil, Podapion chus lapathi. gallicola. now known to occur also in Massachusetts, Maine, Connecticut, Vermont, New York, and Pennsylvania. It feeds on a wide variety of species in the genera Thuja, Chamaecyparts, and Juniperus. Certain varieties of T. occidejitalis and C. obtusa appear to be particularly favored. The adult is light brown with grayish wings and is about 6 mm. long. The beak is short, not quite as long as broad, and there are light, metallic green hairs on the legs and antennae. Eggs are deposited in the soil during May and June, and the larvae feed on the roots of the host plant for the remainder of the season. Winter is spent in the late larval or pupal stage, and the adults appear from early May to July (415). The arborvitae weevil is destructive in both the larval and adult stages, primarily in the larval stage. Damage in nurseries may be severe where infestations occur over a period of many years. In severely infested areas, well over 200 larvae may be found feeding on the roots of a single plant. This results in severe root pruning. Phyllobius oblongus (L.), the European snout beetle, an intro- duced species first recorded in the United States at Rochester, N. Y. in 1923, is now known to occur at least as far west as Ohio. It feeds on a fairly wide variety of hardwoods including elm, maple, willow, cottonwood, pear, apple, and plum. Adults feed on the leaves and young shoots of their hosts; the larvae feed on the roots of various plants. The Japanese weevil, Pseudocneorhinus bifasciatus Roelofs, an introduced species first recorded in the United States at Westville, Conn., in 1920, is now rather widely distributed in the North- eastern States. It feeds on a wide variety of trees and shrubs such as flowering dogwood, hemlock, red bud, azalea, rhododendron, 219. Ple
