螫吃：每樣都來一點

The California harvester ant is a species of ant that lives in the dry, sunny south-west of the United States and northern Mexico. It lives in large colonies, sometimes with thousands of ants, and it forages in the open during the day. It is also known as the ant used in Uncle Milton's Ant Farm.1

Forages during the day, alone or in groups, often moving in columns1
Colonies can have thousands of workers, with an average of about 4,500 ants1

毒液力量

螫

毒液從螫針出來。

牠的毒液有什麼作用？

It stings, and its stings inject venom. The Chumash people of California traditionally swallowed these ants alive, and the venom from their stings caused hallucinations, which was used in coming-of-age ceremonies for boys.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

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

小知識

Around 250 of these ants were considered an effective dose by the Chumash people when they were used in traditional ceremonies.1

This ant is the species used by Uncle Milton's Ant Farm, a popular toy that lets people watch ants dig tunnels.1

Colonies with several queens have been found to have higher average heat tolerance and less variation in heat tolerance, which gives them longer foraging times.1

Most colonies are started and run by a single queen, but some nests have several queens working together, a situation called pleometrosis.1
