Vine weevil plant damage

Black vine weevil has been found to be able to feed on over 140 different plant species. Plant damage can be caused in a number of ways, including adults feeding on leaves (notching of leaf margins) and larvae feeding on the roots, which limits growth and can cause plant death.
