Tarantula hawk is a common name for large spider wasps in the genera Pepsis and Hemipepsis that hunt tarantulas to provision their larvae. They are known for striking blue-black bodies with orange wings and for having one of the most painful insect stings reported in North America.

Classification and naming

The term tarantula hawk refers to spider wasps in the family Pompilidae, especially species in the genera Pepsis and Hemipepsis. The name comes from their habit of hunting tarantulas.

Description

Tarantula hawks are large wasps with metallic blue-black bodies, bright orange wings, and long legs. Some species are among the largest parasitoid wasps in their range.

Life cycle and behaviour

Females hunt tarantulas, sting them into paralysis, and use them as hosts for their offspring. Adults are usually solitary and often feed on nectar, while larvae consume the spider host.

Distribution and habitat

These wasps are found in warm regions worldwide, especially the deserts of the southwestern United States, Mexico, and parts of Central and South America. They are absent from Europe and Antarctica.

Sting and human interaction

Tarantula hawks are known for an exceptionally painful sting, often cited as one of the most painful insect stings. They are not generally aggressive toward humans unless handled or threatened.
