See this bug in the Encyclopedia

Natural Habitat

Gardens, forests, and wetlands where host plants are present

Diet & Feeding

Herbivorous; larvae primarily feed on the leaves of trees, shrubs, and flowers

Behavior Patterns

Notable for their 'looping' locomotion caused by lacking mid-body prolegs. They often freeze in a stiff, straight position to mimic a small twig or stick to avoid predators.

Risks & Benefits

Generally harmless to humans; however, large infestations can cause significant defoliation to garden plants or forest trees. They serve as an important food source for birds and predatory insects.
