Inchworm (Geometer moth caterpillar)

Natural Habitat

Gardens, forests, and residential areas; often found on plants, trees, and occasionally hitching rides on clothing.

Diet & Feeding

Herbivorous; primarily feeds on the leaves of various trees, shrubs, and garden plants.

Behavior Patterns

Characterized by a unique 'looping' walk because they lack middle prolegs. When threatened, they often stiffen and stand at an angle to mimic a small twig or stick.

Risks & Benefits

Generally harmless to humans and pets. While they are important food sources for birds, large populations can cause minor defoliation in gardens or ornamental plants.
