The tarantula hawk is a species of spider wasp which hunts tarantulas as food for its larvae.

Up to two inches (50 mm) long with a blue-black body and bright rust-colored wings, tarantula hawks are among the largest of wasps. The coloring on their wings warns potential predators that they are dangerous (Aposematism). Their long legs have hooked claws for grappling with their victims. The stinger of a female tarantula hawk can be up to 1/3 inch (7 mm) long, and delivers a sting which is rated among the most painful in the insect world.
