Common name: Black vine weevil
Scientific name: Otiorhynchus sulcatus
Hosts: While able to feed on a wide range of herbaceous and woody ornamentals, the black vine weevil does the most damage to yews and rhododendrons. It will also attack strawberry, blackberry, blueberry, and cranberry plants, as well as forsythia, and euonymus.
Black vine weevil can cause damage to susceptible plants at both the adult and larval stages of its life cycle. The larval feeding at the root system does the real damage, with foliar feeding by adults being mostly cosmetic. This insect is found throughout a large part of North America.
