The American Dagger Moth is a medium-sized noctuid with gray, black-streaked wings and a distinctive dagger-like black streak on its forewing. Its caterpillar is a familiar and striking creature: bright yellow with long white or black hair pencils and is commonly encountered in fall. The hairs can cause mild skin irritation in sensitive people.
