Red wood ant

Formica rufa

无害对人无害。不用担心。

会喷或会吐吃：什么都来一点

The red wood ant is a large forest ant that builds big, dome-shaped nests of twigs, grass and pine needles. It lives across much of Europe and northern Asia, from Scandinavia and Great Britain to Lake Baikal. It is special because its colonies can be huge and have several queens, and it can spray formic acid from its abdomen to defend itself.1

怎样认出它

Head and thorax (front body) are red, while the abdomen (rear) is brownish-black.1
Usually has dark patches on the head and the upper part of the thorax, though some individuals are more uniformly reddish.1
Workers measure 4.5 to 9 mm long and have large mandibles (jaws).1
Builds large, conspicuous dome-shaped mounds in woodland clearings.1

常被误认为： Closely related wood ants are hard to separate by eye. Under magnification, the amount of hair is a key clue: this species is hairier than Formica polyctena but less hairy than Formica lugubris.1

毒液之力

会喷或会吐

它会向攻击者喷射刺激性液体。

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。

它害怕时会做什么？

When threatened, workers spray formic acid from their abdomens and defend the nest by guarding entrances and patrolling nearby areas.1

如果它喷到你

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。
如果它喷到你：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

事实

Formic acid was first extracted in 1671 by the English naturalist John Ray, who distilled a large number of crushed ants of this species.1

Wood ants raid the nests of other ants and insects, and some species take captured young back to their own colony as workers.1

Some colonies are huge networks of connected nests, and some of these nests can be several metres high and wide.1

Wood ants collect resin from conifer trees and use it in their nests for structure, protection and antimicrobial defence.1

A large colony may have 100,000 to 400,000 workers and 100 queens.1

Forestry uses this species, which is introduced into an area as a form of pest management.1
