The insects with the spraying butts are fittingly named bombardier beetles.

投弹手甲虫。

Bombardier beetles use the first approach.

庞巴迪甲虫使用第一种方法。

Darwin’s assailant was the bombardier beetle.

攻击达尔文的是庞巴迪甲虫。

The bombardier beetle is no exception: the toads that swallow them can tolerate the caustic spray that Darwin found so distasteful.

庞巴迪甲虫也不例外：吞下它们的蟾蜍可以忍受达尔文认为如此令人反感的腐蚀性喷雾。

She used to be a bossy and boring bombardier and did service in a bomber.

她过去是个专横的，讨厌的投弹手，服役于一架轰炸机。

What also makes them unusual is that, even though the nocturnal beetles are solitary by night, dozens or even hundreds of them—of various bombardier species—snuggle together under rocks during the day.

使它们与众不同的另一个原因是，即使夜间活动的甲虫在夜间是孤独的， 但在白天，数十甚至数百只不同的庞巴迪甲虫会依偎在岩石下。
