Oakworms are Out Feeding on the Leaves of Oak Trees

In late summers, large black caterpillars appear and feed on the leaves of oak trees. Though they may look threatening, the insects are not a threat to the trees. They are orange-striped oakworms, which are quite common in our area. They defoliate a few branches, but seldom harm the trees. Their droppings can cover the ground beneath. If the presence of the worms are bothersome, the best course of action is to remove the infested branches. Otherwise, they will disappear in time.
