Black Vine Weevils damage over 100 different ornamental plants, including broadleaf, evergreen and deciduous trees. While both the adult and larvae can damage plants, the larvae cause the most trouble.
Black Vine Weevil Damage
Black Vine Weevil larvae are small, ½ inch long c-shaped white Grubs that damage plants by tunneling through roots as they feed. The root damage causes leaves to turn yellow, stunted growth, and increasing the risk of root diseases like Phytophthora.
Adult Black Vine Weevils are black or dark slate gray and can grow up to ¾ inch long. They have a short snout, "elbowed" antennae and patches of short hair on their wings, although they cannot fly. Adults chew crescent-shaped notches on the edges of leaves.
Where Black Vine Weevils are Found Geographically
Black Vine Weevils are common throughout the Northern half of the United States, from the Carolinas in the South to Oregon in the West.
