The other predatory insects that go on long hunting-expeditions embrace the prey which they have rendered lifeless, drag it, convey it, each in its own fashion, and, laden with their burden, long try to escape from the bell and to reach the burrow. Disheartened by vain attempts, they abandon it at last. The Scolia does not move her prey, which lies indefinitely on its back at the spot of sacrifice. After drawing her dagger from the wound, she leaves her victim alone and starts fluttering against the walls of the bell, without troubling about it further. Things must happen in the same way in the manure-heap, under normal conditions. The paralyzed morsel is not carried elsewhither, to a special cellar: where the struggle occurred, there it receives, on its spread belly, the egg whence the consumer of the succulent dainty will presently emerge. This saves the expense of a house. It goes without saying that the Scolia does not lay under glass: the mother is too prudent to expose her egg to the dangers of the open air. A second detail strikes me: the fierce persistency of the Scolia. I have seen the fight prolonged for a good quarter of an hour, with frequent alternations of successes and reverses, before the Hymenopteron achieved the requisite position and reached with the tip of her belly the point at which the sting must enter. During her assaults, which are resumed as soon as repelled, the aggressor repeatedly applies the extremity of her abdomen against the grub, but without unsheathing; for I should perceive this by the start of the animal injured by the prick. The Scolia, therefore, does not sting the Cetonia anywhere until the desired point offers beneath the weapon. The fact that no wounds are made elsewhere is not in any way due to the structure of the grub, which is soft and penetrable at all points, except the skull. The spot sought by the sting is no less well-protected than the others by the dermal wrapper.
