If you’re exploring the outdoors in New York and come across the American Dagger Moth caterpillar, exercise extreme caution. This striking creature may look fascinating with its vibrant yellow and black hairs, but it poses a serious risk if handled. The caterpillar’s body is covered in both short tufts and longer, wispy strands that can easily break off and sting upon contact. This can lead to painful hives, burning sensations, and general skin irritation.
