Otiorhynchus sulcatus (Fabricius) - Adult(s) The black vine weevil feeds on many landscape plants such as azalea, rhododendron, euonymus, and liquidambar. Adults have the head elongated into a snout and have elbowed and clubbed antennae. Adults do not fly. Larvae are whitish grubs. Other weevil species may also be present, but may not cause the extensive root damage caused by black vine weevil.
Adults generally feed on foliage. Leaves or flowers appear notched or ragged, and leaves or needles may be clipped from twigs. The most serious damage is done by larvae, which feed on roots and can kill or weaken some plants, especially azalea and rhododendron, increasing damage from root diseases such as Phytophthora. Feeding on branches can cause limb breakage. Feeding galleries may be seen in the crotches of limbs.
