Scientific Name: Actias luna (larva)
Order & Family: Lepidoptera (moths and butterflies); Saturniidae (Giant Silkworm Moths and Royal Moths)
Size: Larvae can reach up to 3 inches (7-8 cm) in length.
Natural Habitat
Deciduous forests, woodlands, and suburban areas with suitable host trees.
Diet & Feeding
Leaves of various deciduous trees, including sweetgum, hickory, sumac, walnut, pecan, and birch.
Behavior Patterns
As a caterpillar, it is primarily engaged in feeding and growing. It will eventually pupate, either in the soil or in a cocoon, to transform into an adult moth. The adult moths are nocturnal.
Risks & Benefits
No risks to humans. As caterpillars, they can defoliate host trees but rarely cause significant damage to mature trees. As adults, they play a minor role in pollination as they visit flowers for nectar, though their primary role is reproduction.
