Asian needle ant

Brachyponera chinensis

只是會痛會痛，但不會對你造成嚴重傷害。

螫

The Asian needle ant is a small stinging ant that is native to Japan and mainland Asia. It has spread to the United States, where it is now common across much of the American South and along the East Coast. It matters because its sting can cause serious allergic reactions in some people, and it crowds out native ants.1

怎麼認出牠

A stinging ant from the ponerine group1
Often nests near termite colonies, which are a reliable food source1
Looks very similar to Brachyponera luteipes, B. nigrita and B. obscurans, so it is often mistaken for them1

常被誤認為： It is commonly mistaken for Brachyponera luteipes, Brachyponera nigrita and Brachyponera obscurans because they look similar. Misidentification can mean people do not realise the seriousness of the sting.1

毒液力量

螫

毒液從螫針出來。

牠的毒液有什麼作用？

Its venom contains proteins that can trigger allergic reactions. The sting is painful and can leave people in distress. In some cases, allergic reactions cause anaphylaxis, a severe whole-body reaction, or urticaria, which is hives.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。

The ant is not aggressive but will sting when disturbed. Its sting can cause anaphylaxis in some people. As it spreads into more urban areas, encounters with people are likely to increase.1

牠害怕時會做什麼？

Although not aggressive, it will sting when it is disturbed.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

小知識

In invaded areas, the native ant Aphaenogaster rudis was reduced by 96%.1

A study in North Carolina found that the Asian needle ant outnumbered all native ant species in most sample areas.1

Workers carry nestmates from one place to another when the colony moves nests. Unlike many ant species, they likely use visual cues rather than pheromone trails to do this.1

Queen ants have a special pouch that stores sperm, so they can mate once and keep reproducing for their whole lives.1

The European Union has listed it as an invasive alien species of Union concern, so it cannot be imported, bred, transported, sold or intentionally released in any EU member state.1
