The tarantula hawk is a very large wasp that hunts tarantulas, which are big hairy spiders. It lives from the southern United States through Mexico and Central America to northern South America, and also on the Caribbean islands. Its sting is among the most painful of any insect.1

Leef in

Southern United States (as far north as Kansas), Mexico, Central America, northern South America and the Caribbean1

Noord-Amerika, Suid-Amerika

Tuis

Females hunt low over the ground, mainly around dusk and dawn to avoid the strong daytime sun. They look for spider burrows, using sight or scent, and may enter them to find prey.1

Lengte

2,4 cm tot 5,1 cm (0,9 in tot 2 in)1

Topspoed

omtrent 45 km/h (28 mph)

Vlieënd, rowwe skatting

Wat eet dit?

Adults hunt tarantulas, almost always from the Theraphosidae family. The wasp stings the spider to paralyse it, and the wasp's larva then eats the paralysed spider.1

Hoe om dit te herken

Black and orange colours, with several colour forms: an orange-winged form, a black-winged form, and in northern South America a form with a dark wing base, dark amber patches and a pale wing tip1
Females are 30–51 mm long; males are 24–40 mm long1
Jerky movements and a strong odour1
Males have 12 antennal segments, which separates them from other Pepsis species, which have 131

Word dikwels verwar met: The black-winged form is hard to tell apart from Pepsis mexicana, but that species is always noticeably smaller. The robber fly Wyliea mydas copies the tarantula hawk's black body and bright orange wings, and makes stinging movements, but it cannot sting.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

Tarantula hawks produce large amounts of venom. A sting causes immediate, intense pain that is short-lived, and it is among the greatest pain recorded for any stinging insect. The venom itself is not very toxic, so its defence works almost entirely through pain.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Only females can sting. The sting is considered the second most painful of any insect sting, scoring 4.0 on the Schmidt sting pain index, compared with 4.0+ for the bullet ant.1

Wat doen dit as dit bang is?

Its black and orange colours, jerky behaviour and strong odour warn predators that it can sting.1

As dit steek

Skraap 'n byangel uit en koel die plek af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer en gebruik sy adrenalienpen (outo-inspuiter) as hy een het.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

The female chooses the spider's size and sex for her eggs. Fertilised eggs go on large spiders and become females, and unfertilised eggs go on male spiders and become males.1

Roadrunners sometimes steal the tarantula from a wasp and leave the wasp unharmed. Others beat the wasp against the ground before eating it.1

The tarantula hawk is the state insect of New Mexico. Almost 10,000 schoolchildren voted for it, and it was made official by a law signed in 1989.1

Wasps of the genus Pepsis are important pollinators of milkweeds, which are poisonous to grazing livestock.1

Mite-breker

Mite: The tarantula hawk's sting is dangerous mainly because its venom is strongly poisonous.

Waarheid: The venom itself is not very toxic. Its main defence is the intense pain of the sting.1
