There is something strangely daunting in the actions of an insect. It moves so directly, with such uncanny precision, with such utter indifference to anything but the end in view. Cannibalism is a rule, almost without exception. The paralysis of prey, so it may remain alive and fresh--though in agony--for weeks on end, is a common practice. The eating piecemeal of still living victims is a matter of course. Absolute mercilessness, utter callousness, incredible inhumanity beyond anything known in the animal world is the natural and commonplace practice of the insects. And these vast cruelties are performed by armoured, machine-like creatures with an abstraction and a routine air that suggests a horrible Nature behind them all. Burl nearly stumbled upon a tragedy. He passed within a dozen yards of a space where a female dung-beetle was devouring the mate whose honeymoon had begun that same day and ended in that gruesome fashion. Hidden behind a clump of mushrooms, a great yellow-banded spider was coyly threatening a smaller male of her own species. He was discreetly ardent, but if he won the favor of the gruesome creature he was wooing, he would furnish an appetizing meal for her some time within twenty-four hours. Burl's heart was pounding madly. The breath whistled in his nostrils--and behind him, the wave of army ants was drawing nearer. They came upon the feasting flies. Some took to the air and escaped, but others were too engrossed in their delicious meal. The twitching little maggots, stranded upon the earth by the scattering of their soupy broth, were torn in pieces. The flies who were seized vanished into tiny maws. The serried ranks of black insects went on. The tiny clickings of their limbs, the perpetual challenges and cross-challenges of crossed antennae, the stridulations of the creatures, all combined to make a high-pitched but deafening din. Now and then another sound pierced the noises made by the ants themselves. A cricket, seized by a thousand tiny jaws, uttered cries of agony. The shrill note of the crickets had grown deeply bass with the increase in size of the organs that uttered it. There was a strange contrast between the ground before the advancing horde and that immediately behind it. Before, a busy world, teeming with life. Butterflies floating overhead on lazy wings, grubs waxing fat and huge upon the giant cabbages, crickets eating, great spiders sitting quietly in their lairs waiting with invincible patience for prey to draw near their trap doors or fall into their webs, colossal beetles lumbering heavily through the mushroom forests, seeking food, making love in monstrous, tragic fashion.
