This species has been particularly abundant on yellow-poplar in eastern Kentucky since 1960. Heavy infestations have also oc- curred in Ohio, West Virginia, Virginia, and Tennessee.

The willow flea weevil, Rhynchaenus mfiyes (LeC), occurs in eastern Canada and south and west through the Eastern States to New Mexico. Willow is its preferred host, but it also feeds on many other hardwoods such as elm, red maple, aspen, red oak, gray and white birch, cherry, shadbush, and apple. The adult is black, broadly elliptical, and about 2 mm. long. The eyes are large and almost meet in front; the antennae are reddish-yellow and elbowed; the scutellum is white; the legs are reddish-yellow; the hind femora are thick and fitted for jumping; and there is a small white spot at the base of the wing covers. In Maine, winter is spent in the adult stage beneath loose bark, under stone walls, in debris, or in the soil. Overwintering adults emerge in early spring, fly to their hosts, and feed by eating cir- cular holes in opening buds and new leaves. Eggs are laid in pits 222
