The black-banded jumper ant is a large ant that can leap up to 10 centimetres, which is far above its own body length. It lives in eastern Australia, including suburbs of Sydney and Brisbane. Its sting is painful and can cause serious allergic reactions in some people, so it is worth knowing how to recognise it.1

It nests in sandy soil, often under a small mound that looks like a molehill, and hides the nest with twigs, leaves and gravel. Nests are found beside a clump of grass or bush, or at the base of a tree. It prefers dry to semi-dry forests and woodlands, mostly on the coastal plains, and has been found in suburbs such as Heathcote and Como in Sydney.1

何を食べるの？

It eats other insects, including caterpillars and spiders, and also drinks honey water. It hunts on plants and trees, and sometimes on the ground. It has been seen preying on the larvae of imperial hairstreak butterflies, even jumping while carrying them.1

見分け方

Mostly black and orange-red in colour.1
The gaster (rear body), head, legs and mesonotum (middle back) are black, while the pronotum, propodeum, petiole and post-petiole are red.1
Mandibles (jaws) are either black or yellow, depending on where the ant lives.1
Workers are 13 to 15 mm long, males 16 to 17 mm, and queens 17 to 19 mm.1
It can leap 76 to 102 mm by suddenly extending its middle and hind legs.1

よくまちがえられるのは： It is often confused with other Myrmecia species. It can be told apart by its bi-coloured thorax and post-petiole, which are yellowish-red and black, and by its yellowish-red node.1

毒パワー

刺す

毒は針から出るよ。

その毒（かむ・刺す毒）はどうなるの？

Its sting is highly venomous and causes intense burning pain. The burning can last for many days, and the sting itches. If the sting is left untreated, it may develop into an ulcer (an open sore). The venom of a close relative, M. pilosula, is among the strongest of all ants and contains acids, enzymes and phospholipases.1

人にとってどれくらい危険？

人への危険: 痛いすごく痛いこともあるけど、深刻になることはほとんどないよ。

A 2011 study of Australian ant allergies found that 265 of 376 participants reacted to the stings of several Myrmecia species, which can cause anaphylaxis (a severe, whole-body allergic reaction). Of these, 15 reacted to this species, while 176 reacted to M. pilosula. The study concluded that Myrmecia species were among four main groups of Australian ants responsible for anaphylaxis.1

こわいとき、どうするの？

When threatened, workers and scouts quickly defend the nest and may react aggressively even to a shadow crossing it, bursting out in short hops to attack.1

知っておく価値あり

データ

It can jump between 76 and 102 mm, which is far more than its own body length.1

Colonies can continue without a queen, because workers can lay fertile eggs.1

It often forages in trees, where it visits the flowers of some eucalyptus and senna plants and may help pollinate them.1

A worker can live for over a year, with a maximum of about 1.3 years.1

Its nests are camouflaged with twigs, leaves, gravel and other plant material.1
