Common Leaf Weevil causes harm primarily through feeding on the leaves and roots of deciduous trees and shrubs, including fruit trees. The insect chews on plant tissues, leading to defoliation and root damage. This impairs the plant’s ability to photosynthesize and absorb nutrients, ultimately compromising plant vigor and productivity.
