The jack jumper ant is a venomous ant native to Australia. It is most common in Tasmania and south-east mainland Australia, and it is known for jumping long distances when it is disturbed. Its sting is usually mild, but it is one of the few ants that can be dangerous to people.1

Leef in

Australia, mostly Tasmania and south-east mainland; widespread in most of Australia; not verified in the Northern Territory1

Australië & Oseanië

Tuis

Jack jumper ants live in open places such as gardens, lawns, pastures, woodlands and dry open forests, usually on fine gravel and sandy soil. In suburbs they build nests in rockeries, cracks in concrete walls and grass, and they are less common in urban areas.1

Lengte

1,1 cm tot 1,6 cm (0,4 in tot 0,6 in)1

Topspoed

omtrent 0,19 km/h (0,12 mph)

Op land, rowwe skatting

Wat eet dit?

Jack jumper ants prey on small insects. They kill other insects by injecting venom through a barbless stinger. Their food also includes nectar.1

Hoe om dit te herken

Black or blackish-red body, sometimes with yellow or orange legs1
Antennae, lower legs and mandibles (jaws) are yellow or orange1
Workers are medium-sized, about 12 to 14 mm long1
Grey, short hair on the body, longer on the back part of the abdomen1
Leaps about 51 to 76 mm when disturbed, and forms mounds of gravel and soil as nests1

Word dikwels verwar met: Other Myrmecia ants, such as M. nigrocincta, also jump when disturbed, so jumping alone does not identify this species.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

The venom is unusually likely to cause allergy for an insect venom. In most people a sting causes only a mild reaction at the site. In people who are allergic, it can cause anaphylaxis, a severe whole-body reaction with a faster heart rate and falling blood pressure.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.

Most stings cause only a mild local reaction, but the jack jumper is one of the few ants that can be dangerous to humans. The venom causes about 90% of ant allergies in Australia. In areas where it lives, up to 3% of people may be allergic, and about half of those can have anaphylaxis, which rarely leads to death. Between 1980 and 2000, four people died from anaphylaxis caused by jack jumper stings, all in Tasmania.1

Wat doen dit as dit bang is?

When disturbed, they become aggressive towards humans, and they can see and follow an intruder from about 1 m away.1

As dit steek

For people prone to severe allergic reactions, the treatment is allergen immunotherapy, also called desensitisation.1
Was en koel die steke 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.

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

Their leaps are about 51 to 76 mm, which is a long jump for an ant of this size.1

They decorate their nests with seeds, soil, charcoal, stones, sticks and small dead invertebrates, which help trap the sun's warmth.1

William Morton Wheeler compared them to 'Lilliputian cavalry galloping to battle' when they were disturbed.1

Workers are gamergates, so they can reproduce with males whether or not a queen is present in the colony.1

Rove beetles of the genus Heterothops often live in jack jumper nests and raise their young there.1
