Creepy crawlies can scare even the best of us! But if you are a brave person who is unafraid of caterpillars, moths, and their friends, then the American Dagger Moth is the perfect companion for you. Endemic to North America, as is given by their name, they have a very short life span, growing from larvae to caterpillars with bright colored hair, to drab-colored adults to eventually finishing their life cycle. However, just because they do not live long, that does not mean they do not live well. Named after the 'dagger' shape made by the black line on their wings, this species can be found very close to home.

This species is found East of the Rocky Mountains. They first came into light in the mid-1800s, when they injured the young son of an American naturalist. Since then, it has existed around us, on trees such as the cedar, oak, and the willow, content to be where it is. However, if you ever see them in caterpillar form, leave them alone! Touching their prickly hairs will result in you ending up in a nasty rash that won't go away for days to come. It is best to avoid them, and instead spend time reading about them with our facts collected for you below, and about other animals such as the puss moth and the purple emperor butterfly.
