Alphabetical List of Critters - Black Vine Weevil

BlackVineWeevilThe Black Vine Weevil, Otiorhynchus sulcatus (Fabricius), is a type of beetle, (native to Europe but also common in North America) belonging to a group that is collectively referred to as root weevils, because the larvae–small and legless grubs–are root feeders (the bark from stems near the ground are sometimes eaten as well). Adults of the Black Vine Weevil hide during the day, and feed at night on the outer edges of leaves, causing a characteristic rounded notch, and the species has a very large host range (100+ kinds of plants), including some trees, fireweed, labrador tea, sheep sorrel, running brambles (Rubus sp.), rhododendron, strawberries, blueberries, cranberries, and many kinds of woody garden plants and flowers. The adult weevil is dull black in color and is unable to fly (its wing covers are fused together). There is only one generation per year.
