"The bombadier beetle has a large oval abdomen, which secretes a caustic fluid. They live in societies, and when they are attacked or alarmed, they discharge this fluid, which not only makes a loud report, but diffuses a disagreeable and penetrating odor: if the liquid strikes the human skin, it produces a blister." &mdash; Goodrich, 1859

"These congregate together under stones, and when disturbed discharge a caustic fluid of an extremely penetrating odor, and so volatile that no sooner does it come in contact with the atmosphere than it passes into a vapour, accompanied by a considerable explosion, during which they seek to escape. When placed on the tongue this guid causes a sharp pain and leaves a yellow spot somewhat similar to that produced by a drop of nitric acid. The Bombardiers are said to be capable of giving off as many as 18 of such discharges at a time." &mdash; Encyclopedia Britanica, 1893.

"Springing Beetles, Elateridae, are narrower and more elongate than the former, and their legs are so short that when they fall on their backs they are as unable to right themselves as a capsized turtle, but by bending the head and thorax backwards, and making use of the prolongation already described, they are enabled to spring to a height fully ten times their own length, and this operation they repeat until they fall on their feet. The noise which accompanies the springing process has earned for them the name of Click Beetles." &mdash; Encyclopedia Britanica, 1893

"The Colorado Beetle is a beetle first described by Thomas Say, in 1824, from specimens found by him near the Upper Missouri. The larva feeds greedily on the potato, and having attracted notice in Colorado for its ravages among the crops of that esculent in the territory, it moved eastward year by year, till in 1874 it had reached the Atlantic seaboard. It is popularly known as the potato bug."&mdash;(Charles Leonard-Stuart, 1911)
