Inchworm (Geometer moth caterpillar)

Natural Habitat

Found worldwide in forests, gardens, and woodlands on host plants such as trees, shrubs, and low-growing vegetation.

Diet & Feeding

Herbivorous; they primarily feed on the leaves of a wide variety of deciduous trees, shrubs, and other plants.

Behavior Patterns

Characterized by a unique "looping" gait caused by having prolegs only at the front and back ends. Many species are masters of mimicry, stiffening their bodies to look like small twigs or stems to avoid predators.

Risks & Benefits

Generally harmless to humans. While most species are beneficial as food for birds, some species can become pests if they occur in large numbers, leading to the defoliation of trees and crops.
