American Dagger Moth Caterpillar

Acronicta americana (caterpillar)

American Dagger Moth Caterpillar

This larval stage feeds on the leaves of many hardwood trees, including maples, oaks, birches, and elms in eastern North American forests and yards. It moves slowly along twigs and foliage, relying on its dense pale hairs and black tufts as a warning to predators. Its diet is entirely plant-based, but the hairs can irritate skin and discourage handling. A notable feature is its bright, fuzzy appearance, which is much more conspicuous than the gray adult moth.
