Fall Webworms
Fall webworm larvae, a north american native, can be seen these days on the Black Walnut trees near the barn of Ivy Creek. Their silky nests are teeming with caterpillars but, while they look like they are being incredibly destructive, they really won't harm a healthy tree. These caterpillars can be distinguished from tent caterpillars by the timing of their appearance (tent caterpillars appear in the spring) and the placement of the nests. Look for the webs of the fall webworm larvae at the ends of branches.
