Horticulture/Otiorhynchus sulcatus

The black vine weevil, Otiorhynchus sulcatus, is native to Europe, but common in North America as well. This weevil is a pest of many garden plants, causing the most damage on evergreen trees and shrubs.

The adult weevil is black with fused wing covers, and is unable to fly. Adults feed at night on the outer edges of leaves, causing the leaves to have a notched margin.

Grubs live below the soil surface, and feed on the roots and on the cambium at the base of the trunk.
