THE RED ANTS
Among the treasures of my piece of waste ground is an ant-hill belonging to the celebrated Red Ants, the slave-hunting Amazons. If you have never heard about these Ants, their practices seem almost too wonderful to believe. They are unable to bring up their own families, to look for their food, to take it even when it is within their reach. Therefore they need servants to feed them and keep house for them. They make a practice of stealing children to wait on the community. They raid the neighboring ant-hills, the home of a different species; they carry away the Ant-babies, who are in the nymph or swaddling-clothes stage, that is, wrapped in the cocoons. These grow up in the Red Ants’ house and become willing and industrious servants.
When the hot weather of June and July sets in, I often see the Amazons leave their barracks of an afternoon and start on an expedition. The column is five or six yards long. At the first suspicion of an ant-hill, the front ones halt and spread out in a swarming throng, which is increased by the others as they come up hurriedly. Scouts are sent out; the Amazons recognize that they are on a wrong track; and the column forms again. It resumes its march, crosses the garden paths, disappears from sight in the grass, reappears farther on, threads its way through the heap of dead leaves, comes out again and continues its search.
At last, a nest of Black Ants is discovered. The Red Ants hasten down to the dormitories, enter the burrows where the Ant-grubs lie and soon come out with their booty. Then we have, at the gates of the underground city, a bewildering scrimmage between the defending Blacks and the attacking Reds. The struggle is too unequal to remain in doubt. Victory falls to the Reds, who race back home, each with her prize, a swaddled baby, dangling from her jaws.
I should like to go on with the story of the Amazons, but I have no time at present. Their return to the nest is what I am interested in. Do they know their way as the Bees do?
Apparently not; for I find that the Ants always take exactly the same path home that they did coming, no matter how difficult it was or how many short cuts might be taken. I came upon them one day when they were advancing on a raid by the side of a garden pond. The wind was blowing hard and blew whole rows of the Ants into the water, where the Fish gobbled them up. I thought that on the way back they would avoid this dangerous bit. Not at all: they came back the same way, and the Fish received a double windfall, the Ants and their prizes.
As I had not time to watch the Ants for whole afternoons, I asked my granddaughter Lucie, a little rogue who likes to hear my stories of the Ants, to help me. She had been present at the great battle between the Reds and the Blacks and was much impressed by the stealing of the long-clothes babies, and she was willing to wander about the garden when the weather was fine, keeping an eye on the Red Ants for me.
One day, while I was working in my study, there came a banging at my door.
“It’s I, Lucie! Come quick: the Reds have gone into the Blacks’ house. Come quick!”
“And do you know the road they took?”
“Yes, I marked it.”
“What! Marked it? And how?”
“I did what Hop-o’-My-Thumb did: I scattered little white stones along the road.”
I hurried out. Things had happened as my six-year-old helper had said. The Ants had made their raid and were returning along the track of telltale pebbles. When I took some of them up on a leaf and set them a few feet away from the path, they were lost. The Ant relies on her sight and her memory for places to guide her home. Even when her raids to the same ant-hill are two or three days apart, she follows exactly the same path each time. The memory of an Ant! What can that be? Is it like ours? I do not know; but I do know that, though closely related to the Bee, she has not the same sense of direction that the Bee possesses.
CHAPTER V
THE MINING BEES
These Bees are generally longer and slighter than the Bee of our hives. They are of different sizes, some larger than the Common Wasp, others even smaller than the House-fly, but all have a mark that shows the family. This is a smooth and shiny line, at the back of the tip-end of the abdomen, a groove along which the sting slides up and down when the insect is on the defensive. The particular species I am going to tell you about is called the Zebra Bee, because the female is beautifully belted around her long abdomen with alternate black and pale-russet scarfs; a simple and pretty dress. She is about the size of the Common Wasp.
She builds her galleries in firm soil, where there is no danger of landslides. The well-leveled paths in my garden suit her to perfection. Every spring she takes possession of them, never alone, but in gangs whose number varies greatly, amounting sometimes to as many as a hundred. In this way she founds what may be described as small townships.
Each Bee has her home, a house which no one but the owner has the right to enter. A good beating would soon call to order any adventuress Bee who dared to make her way into another’s dwelling. Let each keep to her own place and perfect peace will reign in this new-formed society.
Operations begin in April, very quietly, the only sign of the underground works being the little mounds of fresh earth. The laborers show themselves very seldom, so busy are they at the bottom of their pits. At moments, here and there, the summit of a tiny mole-hill begins to totter and tumbles down the slopes of the cone: it is a worker coming up with her armful of rubbish and shooting it outside, without showing herself in the open.
May arrives, gay with flowers and sunshine. The diggers of April have turned themselves into harvesters. At every moment I see them settling, all befloured with yellow, on top of the mole-hills now turned into craters.
The Bee’s home underneath consists first of a nearly vertical shaft, which goes down into the ground from eight to twelve inches. This is the entrance hall. It is about as thick around as a thick lead-pencil.
At the foot of this shaft, in what we might call the basement of the house, are the cells. They are oval hollows, three quarters of an inch long, dug out of the clay. They end in a short bottle-neck that widens into a graceful mouth. All of them open into the passage.
The inside of these little cells is beautifully polished. It is marked with faint, diamond-shaped marks, the traces of the polishing tool that has given the last finish to the work. What can this polisher be? None other than the tongue. The Bee has made a trowel of her tongue and licked the wall daintily and carefully in order to polish it.
I fill a cell with water. The liquid remains in it quite well, without a trace of soaking through. The Bee has varnished the clay of her cell with the saliva applied by her tongue. No wet or damp can reach the Bee-baby, even when the ground is soaked with rain.
The Bee-grub’s rooms are made ready long beforehand, during the bad weather at the end of March and in April, when there are few flowers. The mother works alone at the bottom of her shaft, using her jaws to spade the earth, and her feet, armed with tiny claws, for rakes. She collects the dirt and then, moving backwards with her fore-legs closed over the load, she lifts it up through the shaft and flings it outside, upon the mole-hill, as we have seen. Then she puts the finishing touches with her tongue, and when May comes, with its radiant sunshine and wealth of flowers, everything is ready.
The fields are gay now with dandelions, rock-roses, tansies, daisies, and other flowers, among which the harvesting Bee rolls gleefully, covering herself with pollen. With her crop full of honey and the brushes of her legs all floury with pollen, the Bee returns to her village. Flying very low, almost level with the ground, she hesitates, with sudden turns and bewildered movements. It appears as if she were having trouble to find her own burrow among so many which look exactly alike. But no, there are certain signs known to the insect alone. After carefully examining the neighborhood, the Bee finds her home, alights on the threshold, and dives into it quickly.
What happens at the bottom of the pit must be the same thing that happens in the case of the other Wild Bees. The harvester enters a cell backwards; she first brushes herself and drops her load of pollen; then, turning round, she empties the honey in her crop upon the floury mass. This done, the unwearied one leaves the burrow and flies away, back to the flowers. After many journeys, she has collected enough provisions in the cell. Now is the time to make them up into food, or bake the cake, as we might say.
The mother Bee kneads her flour, mixing with it a little honey. She makes the dough into a round loaf, the size of a pea. Unlike our own loaves, this one has the crust inside and the soft part outside. The middle of the loaf, the food which will be eaten last, when the grub has gained strength, consists of almost nothing but dry pollen. The Bee keeps the softest, nicest part for the outside, from which the feeble grub is to take its first mouthfuls. Here it is all soft crumb, a delicious sandwich with plenty of honey.
She now lays an egg, bent like a bow, upon the round mass of food. If she were like most Honeybees, she would close the house now. But the Zebra Wild Bee is different. She leaves the cells opening into the burrow, so that she can look into them daily and see how her family is getting on. I imagine that from time to time she gives more food to the grub, for the original loaf appears to me a very small amount compared with that served by the other Bees.
At last the grubs, close-watched and well-fed, have grown fat; they are ready for the second stage of Bee life. They are about to weave their wrappers, or cocoons, and change into chrysales. Then, and not till then, the cells are closed; a big clay stopper is built by the mother into the spreading mouth of the cells. Henceforth her cares are over. The rest will come of itself.
If all goes well, the Zebra Bee’s spring family grows up in a couple of months or so; they leave the cells about the end of June, flying off to seek refreshment on the flowers as their mother has done before them.
