Outright predators, of course, I understand. I am among them. There is no denying that the feats of predators can be just as gruesome as those of the unlovely parasites: the swathing and sipping of trapped hummingbirds by barn spiders, the occasional killing and eating of monkeys by chimpanzees. If I were to eat as the delicate ladybug eats, I would go through in just nine days the entire population of Boys Town. Nevertheless, the most rapacious lurk and charge of any predator is not nearly so sinister as the silent hatching of barely visible, implanted eggs. With predators, at least you have a chance.
