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

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

Zer jaten du?
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

Nola ezagutu

  • 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

Askotan honekin nahasten da: 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

Pozoi-ahalmena

Ziztadak

Pozoia ezten batetik ateratzen da.

Zer egiten du bere pozoiak?

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

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: MingarriaBenetan min handia eman dezake, baina ia inoiz ez da larria.

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

Zer egiten du beldurtzen denean?

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

Ziztatzen badu

  • Atera erlearen eztena karrakatuz eta hoztu lekua.
  • Pertsonak arnasa hartzeko zailtasunak baditu, aurpegia edo eztarria hanpatuta baditu, edo zorabiatzen ari dela sentitzen badu, larrialdi alergikoa da: deitu zure larrialdi-zenbakira eta erabili bere adrenalina-autoinjektagailua, baldin badu.

Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak

Egon seguru

  • Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
  • Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
  • Batek ziztatzen bazaitu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

1

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

2

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

3

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

4

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

Mito-hauslea

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

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