Fall Webworms

Dear Michele,
This appears to be a web full of Fall Webworms,
Hyphantria cunea.   Here is a BugGuide image of the caterpillars that are inside the web.  According to BugGuide:  “About 120 species of hardwood trees have been recorded as larval hosts.  In the north, common hosts include alder, apple, ash, birch, Box-Elder (Acer negundo), cherry, elm, mulberry, poplar, willow.  In the south, common hosts include ash, hickory, maple, mulberry, oak, pecan, poplar, redbud, sweetgum, walnut, willow; preferences for different host plant species appear to be regional and seasonal.”
