The Fall Webworm Moth is a small, white moth (sometimes with brown spots) whose caterpillars build conspicuous, large silk webs enclosing the tips of tree branches in late summer. Despite their alarming appearance, infestations rarely kill trees. Introduced to Europe and Asia in the mid-20th century, it became a significant pest there. Adults are attracted strongly to lights and are common from summer through fall.
