Cow Killer Ants are also referred to as Velvet Ants because of their fuzzy bright red or orange appearance. At first glance they look like an ant, but they are actually a species of wingless wasp. The females do not have wings, and are known for an intensely painful sting. They are usually seen running erratically on sandy soil; their vivid colors serve as a warning to stay away. These insects should not be handled, as they will sting, and it is one of the most painful stings you can experience.
