Fall Webworm Moth
Hyphantria cuneaAlso known as Fall Webworm
Fall webworm moths are delicate white insects whose larvae weave conspicuous silk tents around outer branch tips of deciduous trees in late summer and autumn. Unlike tent caterpillars that build nests in tree crotches, these caterpillars envelop entire clusters of foliage within protective webbing to feed safely inside. Adults emerge in spring and summer, displaying silky white wings that range from immaculate pure white to heavily speckled with dark brown spots.

Responsible observation
- Spotting Webs: Look for large silk webs enclosing leaf clusters on branch tips in late summer.
- Night Observing: Adults fly at night and are frequently attracted to artificial lights and blacklights.
- Nest ID: Distinguish from tent caterpillars by noticing webs at branch ends rather than tree forks.
