In this educational video, ISA Certified Arborist Wes Rivers explores the impact of the oak leaf skeletonizer caterpillar on post oak leaves. Wes provides an in-depth examination of the damage caused by these pests. He focuses on a minor example of feeding damage on a single leaf. He explains how large populations of these insects can result in entire canopies appearing skeletonized. This is a phenomenon witnessed in late summer and early fall of 2022.
Wes presents a larva of the oak leaf skeletonizer moth. He explains that this stage of life is responsible for damaging the oak trees. These larvae hatch on the oak leaves in the spring. They begin feeding on the flesh of the leaves with their rasping mouthparts, leaving behind a dense, fibrous skeletonized leaf.
Emphasizing the vast impact of these pests when they occur in high numbers, he reveals that oak trees can look almost defoliated or dead due to the extensive damage. If viewers suspect the presence of these pests on their trees, they are advised to seek expert guidance from the ISA certified arborists at TreeNewal.
The video concludes by identifying another sign of oak leaf skeletonizer infestation – black pellets, which are droppings from the caterpillars. Droppings found under trees, on cars, patios, and pool areas. It serves as a strong indicator of these pests feeding on your trees.
