Project Description
Imported Willow Leaf Beetle Damage
Adults are oval, stout, metallic, greenish-blue beetles which make noticeable holes through the leaves. They first appear in mid-May and are present off and on throughout the summer. Larvae hatch, feed together in rows, and remove only the leaf surface to leave a skeleton of leaf veins. Skeletonized leaves become brown. Larvae are jet black; tiny at first but when full grown are 1/4 inch long. More than one generation occurs. Winter hibernation is in the same places as for the weevils.
