Yellow tussock moth caterpillar

Trees, shrubs, gardens, and buildings near vegetation; commonly found in temperate regions. This larva may be wandering to pupate.

Chews leaves from many deciduous trees and shrubs, including oak, willow, fruit trees, and ornamentals.

Larvae are active mostly at night and may wander on walls or other surfaces before pupating. Dense tufts and long hairs provide defense; adults emerge as moths.

Its hairs can cause itchy, irritating dermatitis in sensitive people, so avoid handling it. It contributes to food webs, while heavy infestations can defoliate ornamental or forest trees.
