Why are insects of this tribe so often eaten by fishes?

Because all such as are abundant in summer are frequently blown into the water, where they become easy prey. Thus, the brown beetle, or cockchaffer, the fern-fly, and the grey beetle, are devoured in great numbers. But there is hardly an insect that flies, including the wasp, the hornet, the bee, and the butterfly, that does not become at some time the prey of fishes. So voracious are the grubs of some beetles,that the younger ones, when so gorged with those they have devoured, as scarcely to be able to move without bursting, are said, by Kirby and Spence, " often to take advantage of the helpless inactivity into which the gluttony of their maturer comrades has thrown them, and from mere wantonness, it should seem, when in no need of other food, pierce and devour them."

Some beetles are, however, very abstemious. Thus, the rose-chaffer has been kept alive more than eight years, by being fed on crusts of bread soaked in water.

Why was the beetle so often introduced in the buildings of the ancient Egyptians?

Because it was, to all appearance, a highly sacred animal. In the Egyptian tombs, it is found in great variety: of basalt, verde antico, or other stones, and of baked clay. Some have hieroglyphics on them, which no doubt contain some particular prayers, or the commemoration of striking events in the life of the deceased. It is supposed, that the Egyptians hung the beetle to their necks when they went to war; but of this we have no clear proofs. Belzoni mentions a circumstance which, he thinks, will solve the doubt. The beetles are of such a peculiar form, that if they were among the ornaments of the warriors, they would be easily distinguished. He observed a solitary instance of this kind. There is a sitting figure in the tomb of Samethis, which he discovered in the valley below Bebau el Malook, that, by its splendid dress and ornaments, may be intended to represent a king. It has a square plate of basalt hung to its neck, with an obelisk in the centre, and a figure on each side of it. He believes the above plate to be the only one that was ever found of the king. It has the form of an Egyptian temple, and in the centre is an elevated beetle on a boat, guarded by two figures, one at each side; and, on the reverse of the beetle, is an inscription over a boat, on which are two other figures, exactly like the former. The plate has the holes by which it was hung to a chain or string. Belzoni found also other beetles, with human heads, which he had never seen before.

Why is the dung-beetle also called the dorr?

Because, in old times, dorr was a stupid,blundering fellow; and, to dorr, was to ding or trouble with noise; both meanings applicable to the heedless flight, and loud noise, made in all the transits of this dung beetle. Such is the conjecture of Mr. Knapp, in his Journal of a Naturalist, who also speaks of dung beetles as clocks - " as the boys call them, a corruption, he thinks, from cloax, a vault, a creature from below, which might signify its subterranean residence." Or, burrowing in the filth and ordure, as it does, the epithet clocca, the offspring of a common shore, or jakes, would not have been insignificant of its origin and habits."
