蜇伤吃：什么都来一点

The Florida harvester ant is a relatively large ant that lives in the sandy scrub and coastal areas of Florida and the Atlantic coast of the eastern United States. It is the only Pogonomyrmex harvester ant found on the US east coast. Its sting is painful and highly toxic, but the ant is shy and rarely stings unless it is trapped against skin.1

首页

It nests in well-drained sandy soils in Florida scrub, xeric shrublands, grasslands, woodlands and intact coastal dunes. It prefers open sandy ground with sparse plants that gets full sun, so people are most likely to see its nest mounds in these open sandy areas.1

它吃什么？

It eats mainly seeds and insects. Workers prefer protein-rich insect prey over seeds, but seeds wider than 1 to 1.4 mm are too big for workers to crack open.1

怎样认出它

A relatively large harvester ant. Workers range from 6.35 mm to 9.52 mm long.1
The nest has a flat mound with no plants growing around it, decorated with bits of debris and charred plant matter.1
Queens and the largest workers, called majors, have disproportionately large heads.1
It is a highly active ant that is out during the day.1

它的毒液会造成什么？

Its stinger delivers a potent, painful neurotoxic venom, which attacks the nerves. The venom is very toxic: in laboratory tests on mice, the dose that killed half the mice (the LD50) was 0.42 micrograms per gram of body weight, which is comparable to the most toxic snake venoms. Each sting delivers only a small amount of venom.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Dozens of stings are needed to cause potential harm to a healthy adult. The ant is docile and reluctant to sting unless forced to, usually when it is trapped against the skin.1

它害怕时会做什么？

It stings when it is trapped against the skin, and is otherwise reluctant to sting.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。

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

Its stinger is barbed. When it stings, the stinger and venom sac can stay stuck in the skin and keep pumping venom, and the ant dies because its insides are damaged when the stinger is pulled out.1

Mature nests are very deep, usually 2.5 to 3.0 metres underground, with seeds stored in large flat granaries about 40 to 100 cm below the surface.1

Unlike most harvester ants, this species often moves its entire nest once a year, relocating about 4 to 10 metres along an established foraging trail.1

A colony must reach about 700 or more workers before it becomes sexually mature and starts producing winged reproductives.1

Mating takes place on the ground. Males fly in from other nests to mate with queens on the surface of the parent nest, while hundreds of workers swarm around the nest.1

Some ants can be infected by a parasitic fungus, Myrmicinosporidium durum, which turns the ant's outer body a near black colour.1

宝宝: A colony starts when a newly mated queen founds a new nest. She does not feed outside the nest, relying on her fat reserves and wing muscles to raise her brood.1
