Tussock Moth Caterpillar (likely White-marked Tussock Caterpillar or similar species)

Natural Habitat

Found in deciduous and mixed forests, orchards, and urban areas. They feed on a wide variety of trees and shrubs.

Diet & Feeding

Herbivorous. Larvae (caterpillars) feed on the leaves of many hardwood trees including oak, maple, birch, apple, and various fruit trees.

Behavior Patterns

Caterpillars are often solitary feeders and are easily recognized by their distinctive tufts of hair. They move by crawling. Before pupating, they construct a cocoon. Adults are moths, with females being flightless and remaining on their cocoons to lay eggs.

Risks & Benefits

Potential risks include skin irritation or allergic reactions in some individuals upon contact with the caterpillar's urticating hairs (which are the bristly tufts on its back). These hairs can cause a rash, itching, and swelling. They are not typically considered a major pest in healthy ecosystems, but can defoliate trees during outbreaks. As part of the food chain, they serve as food for birds and other predators.
