Fall Webworms

As a result of Diane’s last post about bagworms, we received this question: Is that what shows up later in the summer on trees that look like LARGE spider webs? If not, what's that? The answer is no. What you are seeing later in the summer are actually fall webworms (Hyphantria cunea). Although the webbing looks bad and the adult caterpillars devour many leaves, the tree is rarely in danger because it has had ample time to store food for the winter. For more information and control methods, see: http://www.ces.ncsu.edu/depts/ent/notes/O&T/trees/note46/note46.html
