The attractive Io moth caterpillar is also well-known because of its painful sting. But like many of the other saturniid moths, is less common now in parts of its range. With the exception of Cape Cod and some of the Massachusetts islands, it is now rare in New England where it was once common, and its populations have declined in most of the Gulf States since the 1970s.
