Fall webworms are sometimes confused with Eastern tent caterpillars, which only occur in the spring and are most common on wild cherry trees. Eastern tent caterpillars form their webs near the trunk of a tree, usually where a branch meets the trunk. Fall webworm webs are formed at the ends of branches and do not appear until mid summer.
