The Wattle Cup Caterpillar (Calcarifera ordinata) is a moth of the family Limacodidae. It is widespread in northern Australia, south to Geraldton, Alice Springs and Brisbane. The wingspan is about 30 mm. Adults are creamy brown with lines of dots on the forewings. The hind wings are pale brown. The cocoon is formed on a leaf. It is spun out of silk in a small sphere, then covered in a liquid that sets like a tiny ball. It has an extremely potent sting, described as being "worse than three wasp stings".
