First noted on grapevines in Germany, these weevils, aka BVW, have now spread across Southern Canada and the Northern United States. Their oblong oval shape with slate-colored or black with elbowed antennae distinguish them from other weevils with a similar appearance.
Symptoms: Adult weevils attack a wide variety of trees and bushes including hemlock trees, yews and other broad-leaf evergreens like rhododendrons and azaleas. Typical damage consists of notches along the perimeter of the leaves. Rapid asexual reproduction by the females means their populations can quickly grow to cause extensive damage and kill trees and plants. They now extend throughout Ohio. They do not fly but spread by walking. They are difficult to control due to their larvae emerging from the soil where the females lay their eggs.
