Hardwood Defoliator LP link collection
Hardwood defoliators are insects that feed on the leaves of hardwood trees. Most are caterpillars that hatch in spring and feed through summer, stripping trees of their foliage. While a single year of defoliation rarely kills a healthy tree, repeated or heavy infestations can weaken trees and make them vulnerable to other pests and disease.
