Dinosaur ant

Nothomyrmecia macrops

無害對人無害。不用擔心。

螫吃：每樣都來一點

The dinosaur ant is one of the rarest ants in the world. It is the only species in its genus and lives in woodland in South Australia. Scientists call it a 'living fossil' because its body is so old-fashioned.1

分布在

South Australia, Australia, in mallee and Eucalyptus woodland. Its full range is unknown.1

It nests in old-growth mallee woodland and Eucalyptus woodland. Colonies are very small, with only 50 to 100 individuals in each nest. Pictures of the ant are stencilled on the streets of Poochera, the town where it was rediscovered.1

長度

9,7 mm 到 1,1 cm (0,4 in 到 0,4 in)1

最高速度

大約 0,18 km/h（0,11 mph）

牠吃什麼？

Workers collect arthropod prey and sweet substances such as honeydew from scale insects and other Hemiptera. They forage alone at night and use their vision to find food.1

怎麼認出牠

Medium-sized ant, 9.7 to 11 mm long.1
Mandibles (jaws), clypeus (part of the 'face'), antennae and legs are pale yellow.1
Body hairs are yellow, long and abundant on the body, and shorter on the antennae and legs.1
Workers are strictly nocturnal, active mainly at night, and forage alone.1

常被誤認為： It shows similar features to Myrmecia and somewhat resembles weaver ants (Oecophylla). The fourth abdominal segment of Myrmecia is tubulate (tube-shaped), but in the dinosaur ant it is non-tubulated, which helps separate the two.1

毒液從螫針出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

It has a long, retractable sting at the rear of the abdomen, which can give people a painful sting.1

牠害怕時會做什麼？

It uses its retractable sting when threatened, and workers release chemical alarm signals.1

如果牠螫人

清洗並冷敷螫傷處。
如果傷者呼吸困難、臉部或喉嚨腫脹，或覺得快要昏倒，這就是過敏急症：打緊急電話。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠螫了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

牠有多快？

值得知道

小知識

Scientists regard it as the most plesiomorphic (old-fashioned) ant alive, and it is called a 'living fossil'.1

Poochera is perhaps the only town in the world that relies on ant-based tourism.1

After its first collection in 1931, it was not seen again until 1977, when it was found about 1,300 km from the original site.1

It is the only known ant species with both a sting and a 'waist', meaning it has no postpetiole between the first and second gastral segments.1

Queens have non-functional, stubby wings, while male wings are long and fully developed.1

學名: Nothomyrmecia macrops
類群: 螞蟻
家人: Formicidae2
排序: Hymenoptera
各大洲: 澳洲與大洋洲
寶寶: The queen mates with one or more males, then hunts for food while the brood develops. Eggs are subspherical and non-adhesive. Two queens may found a colony together, but only one remains after the first workers are raised.1
牠在野外的狀況: Critically Endangered1
