There is another marvellous point about the meal of the Anthrax-grub. The Bee-grub remains alive until the very end. Were she really dead it would, in less than twenty-four hours, turn a dirty-brown colour and decompose. But during the whole fortnight that the meal lasts, the butter-colour of the victim continues unaltered, and there is no sign of putrefaction. Life persists until the body is reduced to nothing. And yet, if I myself give her a wound, the whole body turns brown and soon begins to rot. The prick of a needle makes her decompose. A mere nothing kills it; the atrocious draining of its strength does not. The only explanation I can suggest is this, and it is no more than a suggestion. Nothing but fluids can be drawn by the sucker of the Anthrax through the unpierced skin of the Bee-grub: no part of the breathing-apparatus or the nervous system can pass. As these two essentials remain uninjured, life goes on until the fluid contents of the skin are entirely exhausted. On the other hand, if I myself injure the larva of the Bee, I disturb the nervous or the air-conducting system, and the bruised part spreads a taint all over the body. Liberty is a noble possession, even in an insignificant grub; but it has its dangers everywhere. The Anthrax escapes these dangers only on the condition of being, so to speak, muzzled. It finds its own way into the Bee’s dwelling, quite independently of its mother. Unlike most of the other flesh-eating larvæ it is not fixed by its mother’s care at the most suitable spot for its meal. It is perfectly free to attack its prey where it chooses. If it had a set of carving-tools, of jaws and mandibles, it would meet with a speedy death. It would split open its victim and bite it at random, and its food would rot. Its freedom of action would kill it. II THE WAY OUT
