Tussock Moth Caterpillar (likely Sycamore Tussock Moth)

Deciduous forests and urban areas, specifically on or near sycamore and London plane trees.

The larvae feed exclusively on the leaves of Sycamore (Platanus occidentalis) and London Plane trees.

They are solitary feeders that produce one to two generations per year; they often crawl down trunks to pupate in hair-covered cocoons in leaf litter or bark crevices.

The hairs (setae) can cause skin irritation or 'urticaria' in sensitive individuals if handled. Ecologically, they serve as a food source for birds and predatory insects.
