Main Page | See live article | Alphabetical index Female velvet ant Mutillidae Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hymenoptera Family: Mutillidae Multillidae or velvet ants, also known as cow killers, are not actually ants, but a type of wasp. They get their name from the hair that grows on their back. The hair ranges from red and black to completely white. Their shell is very tough, providing protection against wasp and bee stings. The males have wings, but the females are completely wingless. They are generally accepted as being the American insect that provides the most painful sting. It is said (wrongly) that their venom is powerful enough to kill a cow, hence their name, "cow killers." The earliest-known velvet ants come from 25-40 million year old amber from the Dominican Republic. This article is from Wikipedia.
