A female wasp searches the ground and/or vegetation for a spider, and upon finding one, stings it, paralyzing the spider. The targeted spider is typically unable to kill the wasp, because the wasp can just fly out of reach, so at best the spider fights fiercely to escape. [14]
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas.Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it into a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host.
Some caterpillars even bite the female wasps that approach them. Some insects secrete poisonous compounds that kill or drive away the parasitoid. Ants that are in a symbiotic relationship with caterpillars, aphids or scale insects may protect them from attack by wasps. [18] [19] Parasitoid wasps are vulnerable to hyperparasitoid wasps.

Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While the majority of Hymenoptera stings are locally painful, their associated venom rarely cause toxic reactions unless ...
