The common bombardier beetle is a small ground beetle, about the size of a grain of rice. When disturbed, it sprays a hot, explosive-sounding chemical mix from its rear end to drive attackers away. It lives in parts of Europe, central and west Asia, and northern Africa, including southern England and southern Wales.1

毒液力量

噴射或吐出

牠會對攻擊者噴出或吐出刺痛的液體。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

牠害怕時會做什麼？

When disturbed, it shoots a liquid from two glands at its rear end. The two chemicals mix in a firing chamber, where they explode and harm the attacker.1

如果牠噴到你

被會螫人的毛毛蟲毛刺到時：用膠帶把毛黏起來，再清洗皮膚。不要搓揉。
被咬時：清洗並冷敷。如果傷者覺得不舒服或容易流血，要就醫。

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。
如果被牠噴到：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

牠有多快？

一隻陸龜 大約 0,3 km/h (0,19 mph)

Common bombardier beetle 大約 0,39 km/h (0,24 mph)

一個正在走路的人 大約 5 km/h (3,1 mph)

值得知道

小知識

Its defence is a chemical spray. Two substances from separate glands mix with enzymes in a firing chamber and explode.1

Its name comes from a Latin word meaning crackle, because it makes a crackling noise.1
