"Years and years ago, there lived in some fragrant-leaved orange-trees in Australia some white cottony cushion insects whose life was untroubled by other cares than those of eating and of looking after the children. As each insect was fastened for life on the leaf or twig that supplied it with all the food it needed, which was simply an occasional drink of sap, and as the white insects always died before their children were born, neither of these cares was very harassing. On thousands of other similar fragrant-leaved orange-trees in Australia lived millions of other similar white insects. And for a long time this race of white insects enjoyed life. Those were happy days. But on a time there came into one of the trees a few small red beetles, who eagerly and persistently set about the awful business of eating the defenceless white insects. From this tree the red beetles, or the children of them, went to other trees where white insects lived, and with unrelenting rapacity and uncloyed appetite ate all the white insects they could find. And so in other trees; and finally, with years, the red beetles had invaded all of the thousands of fragrant-leaved orange-trees in Australia, and had eaten nearly all of the millions of white insects. "One day a very small orange-tree was taken out of the ground in Australia and sent with many others across the ocean to California. On this small tree there were a few of the white insects. The little tree was planted again in California and soon put out many fresh fragrant leaves. The white insects were astonished and rejoiced that day after day went by without the appearance of any red beetles. The white insects increased in numbers; there were thousands of fragrant-leaved orange-trees in California, and in a few years there were millions of white insects in them. One morning a man stood among the trees and said, 'Confound these bugs; they'll ruin me; what shall I do?' and a man who knew said, 'Get some red beetles from Australia.' So this orange-grower, with some others, paid a man to go to Australia and collect some live red beetles. The collector went across the ocean, three weeks' steady steaming, and sent back a few of the voracious little beetles in a pill box. They were put into a tree in a California orange-orchard in which there were many cottony cushion scale insects. The red insects promptly began eating the white ones; and their children and grandchildren and great-grandchildren have kept up this eating ever since. And so the orange-growers never tire of telling how the red beetles (whose name is Vedalia) were brought from Australia to save them from ruin by the white insects (whose name is Icerya)."
