蜇伤吃：什么都来一点

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

生活在

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

它吃什么？

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

怎样认出它

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

常被误认为： 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

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

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

它害怕时会做什么？

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

如果它蜇人

清洗并冷敷蜇伤处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

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
