![]() ![]() Mental discipline simply does not work in these situations." In terms of scale, the wasp's sting is rated near the top of the Schmidt sting pain index, second only to that of the bullet ant, and is described by Schmidt as "blinding, fierce shockingly electric". One researcher described the pain as ".immediate, excruciating, unrelenting pain that simply shuts down one's ability to do anything, except scream. grossa-is among the most painful of all insects, though the intense pain only lasts about five minutes. However, the sting-particularly that of P. Tarantula hawk wasps are relatively docile and rarely sting without provocation. Both species have bright orange wings that become transparent near the tip. grossa have metallic blue bodies and reddish antennae, which separates them from P. The two species are difficult to distinguish, but the majority of P. Eighteen species of Pepsis and three species of Hemipepsis are found in the United States, primarily in the deserts of the southwestern United States, with Pepsis grossa (formerly Pepsis formosa) and Pepsis thisbe being common. In the latter, Pepsis species have been observed from as far north as Logan, Utah and south as far as Argentina, with at least 250 species living in South America. ![]() Worldwide distribution of tarantula hawks includes areas from India to Southeast Asia, Africa, Europe, Australia, and the Americas, with the genus Pepsis entirely restricted to the New World. Females are not very aggressive, in that they are hesitant to sting, but the sting is extraordinarily painful. The males can become resident defenders of the favorable reproduction spots for hours into the afternoon. Male tarantula hawks have been observed practicing a behavior called hill-topping, in which they sit atop tall plants and watch for passing females ready to reproduce. Both males and females feed on the flowers of milkweeds, western soapberry trees, or mesquite trees. While the wasps tend to be most active in the daytime in summer, they tend to avoid high temperatures. Finally, the wasp becomes an adult and emerges from the spider's abdomen to continue the life cycle.Īdult tarantula hawks are nectarivorous. When the wasp larva hatches, it creates a small hole in the spider's abdomen, then enters and feeds voraciously, avoiding vital organs for as long as possible to keep the spider alive. Sex of offspring is determined by fertilization fertilized eggs produce females, while unfertilized eggs produce males. The female tarantula hawk wasp stings a tarantula between the legs, paralyzes it, then drags the prey to a specially prepared burrow, where a single egg is laid on the spider's abdomen, and the burrow entrance is covered. The stinger of a female Pepsis grossa can be up to 12 mm ( 15⁄ 32 in) long, and the powerful sting is considered one of the most painful insect stings in the world. Their long legs have hooked claws for grappling with their victims. The vivid coloration found on their bodies, and especially wings, is an aposematism, advertising to potential predators the wasps' ability to deliver a powerful sting. These wasps grow up to 6.5 centimetres ( 2 + 1⁄ 2 in) long, making them among the largest of wasps, and have blue-black bodies and bright, rust-colored wings (other species have black wings with blue highlights). They are found on all continents other than Antarctica. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food a single egg is laid on the prey, hatching to a larva which eats the still-living host. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. ![]()
