Velvet Ants, a.k.a. Cow Killers Ants
Dasymutilla occidentalis
Although commonly referred to as the red velvet ant (and in some cases cow killer ant), this name is misleading because velvet ants are actually wasps. They get the "velvet" part of their name from the very fuzzy females, which are wingless and often brightly colored.

Habits
Female cow killer ants dig into the nesting chambers of ground-nesting bees and wasps and lay their eggs on the larvae inside. When the immature velvet ant is born, it eats its host and then spins its cocoon within the pupal case of its host.
Habitat
Female cow killer ants are typically seen running somewhat erratically on the ground, especially on bare or sandy areas in the warm summer months. These pests will occasionally enter structures for insect prey. Male velvet ants are often found on flowers, although some species are nocturnal.
Threats
Female velvet ants have a very potent sting that has earned them the nickname "cow-killer." Male red velvet ants lack a stinger but have wings.
Velvet Ant Prevention
Red velvet ants are solitary and usually found only one at a time. To avoid these stinging ants, contact a pest management professional to safely remove any cow killer ants found in your home.
