Hyphantria cunea
The Fall Webworm Moth is a fuzzy little insect that loves to spin big webs in trees. These webs can look like fluffy cotton candy and are home to many caterpillars that turn into beautiful moths.
Habitat: Forests
The Fall Webworm Moth has a fuzzy, stout white body and mostly pure white wings, though some individuals exhibit small, scattered black spots. It is visually distinct from most other white moths by its hairiness and often unblemished white appearance.
