Ants are disagreeable insects in any country, but especially so in warm tropical climates. Their ugly appearance, their destructive habits, but, above all, the pain of their sting, or rather bite – for ants do not sting as wasps, but bite with the jaws, and then infuse poison into the wound – all these render them very unpopular creatures. A superficial thinker would suppose that such troublesome insects could be of no use, and would question the propriety of Nature in having created them. But when we give the subject a little attention, we find that they were not created in vain. Were it not for these busy creatures, what would become of the vast quantities of decomposing substances found in some countries? What would be done with the decaying vegetation and the dead animal matter? Why, in many places, were it not consumed by these insects, and reorganised into new forms of life, it would produce pestilence and death; and surely these are far more disagreeable things than ants.
Of ants there are many different kinds; but the greatest number of species belong to warm countries, where, indeed, they are most useful. Some of these species are so curious in their habits, that whole volumes have been written about them, and naturalists have spent a lifetime in their study and observation. Their social and domestic economy is of the most singular character, more so than that of the bees; and I am afraid here to give a single trait of their lives, lest I should be led on to talk too much about them. I need only mention the wonderful nests or hills which some species build – those great cones of twenty feet in height, and so strong that wild bulls run up their sides and stand upon their tops without doing them the least injury! Others make their houses of cylindrical form, rising several feet from the surface. Others, again, prefer nesting in the trees, where they construct large cellular masses of many shapes, suspending them from the highest branches; while many species make their waxen dwellings in hollow trunks, or beneath the surface of the earth. There is not a species, however, whose habits, fully-observed and described, would not strike you with astonishment. Indeed, it is difficult to believe all that is related about these insects by naturalists who have made them their study. One can hardly understand how such little creatures can be gifted with so much intelligence, or instinct, as some choose to call it.
Man is not the only enemy of the ants. If he were so, it is to be feared that these small insignificant creatures would soon make the earth too hot for him. So prolific are they, that if left to themselves our whole planet would, in a short period, become a gigantic ants’ nest?
Nature has wisely provided against the over increase of the ant family. No living thing has a greater variety of enemies than they. In all the divisions of animated nature there are ant-destroyers —ant-eaters! To begin with the mammalia, man himself feeds upon them – for there are tribes of Indians in South America, the principal part of whose food consists of dried termites, which they bake into a kind of “paste!” There are quadrupeds that live exclusively on them, as the ant-bear already described, and the pangolins, or scaly ant-eaters of the Eastern continent. There are birds, too, of many sorts that devour the ants; and there are even some who make them exclusively their food, as the genus Myothera, or “ant-catchers.” Many kinds of reptiles, both snakes and lizards, are ant-eaters; and, what is strangest of all, there are insects that prey upon them!
No wonder, then, with such a variety of enemies that the ants are kept within proper limits, and are not allowed to overrun the earth.
The observations just made are very similar to those that were addressed by Doña Isidora to the little Leona, one day when they were left alone. The others had gone about their usual occupation of bark-cutting, and these, of course, remained at home to take care of the house and cook the dinner. That was already hanging over a fire outside the house; for in these hot countries it is often more convenient to do the cooking out-of-doors.
Doña Isidora, busy with some sewing, was seated under the shadow of the banana-trees, and the pretty little Leona was playing near her. Leona had been abusing the ants, partly on account of their having so frightened Leon, and partly because one of the red species had bitten herself the day before; and it was for this reason that her mother had entered into such explanations regarding these creatures, with a view of exculpating them from the bitter accusations urged against them by Leona. Talking about ants very naturally led them to cast their eyes to the ground to see if any of the creatures were near; and sure enough there were several of the red ones wandering about. Just then the eyes of Doña Isidora rested upon a very different insect, and she drew the attention of her daughter to it. It was an insect of considerable size, being full an inch in length, with an elongated oval body, and a small flat head. From the head protruded two great horny jaws, that bore some resemblance to a pair of calliper compasses. Its legs were short and very unfitted for motion. Indeed they were not of much use for that purpose, as it could make very little way on them, but crawled only sidewards, or backwards, with great apparent difficulty. The creature was of a greyish or sand colour; and in the sand, where it was seated, it might not have been observed at all had not the lady’s eyes been directed upon the very spot. But Doña Isidora, who was a very good entomologist, recognised it; and, knowing that it was a very curious insect, on this account called the attention of her daughter to it.
“What is it, mamma?” inquired the little Leona, bending forward to examine it.
“The ant-lion.”
“The ant-lion! Why, mamma, it is an insect! How then can it be called lion?”
“It is a name given it,” replied the lady, “on account of its fierce habits, which, in that respect, assimilate it to its powerful namesake, – the king of the beasts; and, indeed, this little creature has more strength and ferocity in proportion to its size than even the lion himself.”
“But why the ant-lion, mamma?”
“Because it preys principally on ants. I have said there are insect ant-eaters. This is one of them.”
“But how can such a slow creature as that get hold of them? Why the ants could crawl out of its way in a moment!”
“That is true. Nevertheless it manages to capture as many as it requires. Remember ‘the ace is not always to the swift.’ It is by stratagem it succeeds in taking its prey – a very singular stratagem too. If you will sit back and not frighten it, I have no doubt it will soon give you an opportunity of seeing how it manages the matter.”
Leona took a seat by the side of her mother. They were both at just such a distance from the ant-lion that they could observe every movement it made; but for a considerable time it remained quiet; no doubt, because they had alarmed it. In the interval Doña Isidora imparted to her daughter some further information about its natural history.
“The ant-lion (Myrmeleori),” said she, “is not an insect in its perfect state, but only the larva of one. The perfect insect is a very different creature, having wings and longer legs. It is one of the neuropterous tribe, or those with nerved wings. The wings of this species rest against each other, forming a covering over its body, like the roof upon a house. They are most beautifully reticulated like the finest lace-work, and variegated with dark spots, that give the insect a very elegant appearance. Its habits are quite different to those which it follows when a larva, or in that state when it is the ant-lion. It flies but little during the day, and is usually found quietly sitting amongst the leaves of plants, and seems to be one of the most pacific and harmless of insects. How very different with the larva – the very reverse – See!”
Doña Isidora pointed to the ant-lion that was just then beginning to bestir itself, and both sat silent regarding it attentively.
First, then, the little creature going backwards, and working with its callipers, traced a circle on the surface of the sand. This circle was between two and three inches in diameter. Having completed it, it now commenced to clear out all the sand within the circle. To accomplish this, it was seen to scrape up the sand with one of its fore-feet, and shovel a quantity of it upon its flat head; then, giving a sudden jerk of the neck, it pitched the sand several inches outside the traced circumference. This operation it repeated so often, and so adroitly, that in a very short time a round pit began to show itself in the surface of the ground. Wherever it encountered a stone, this was raised between its callipers and pitched out beyond the ring. Sometimes stones occurred that were too large to be thrown out in this way. These it managed to get upon its back, and, then crawling cautiously up the sides of the pit, it tumbled them upon the edge and rolled them away. Had it met with a stone so large as to render this impossible, it would have left the place, and chosen another spot of ground. Fortunately this was not the case, and they had an opportunity of watching the labour to its conclusion.
For nearly an hour they sat watching it – of course not neglecting their other affairs – and, at the end of that time, the ant-lion had jerked out so much sand, that a little funnel-shaped pit was formed nearly as deep as it was wide. This was its trap, and it was now finished and ready for action.
Having made all its arrangements, it had nothing more to do than remain at the bottom of the pit and wait patiently until some unfortunate ant should chance to come that way and fall in; and where these insects were constantly wandering over the ground, such an accident would, sooner or later, be certain to take place.
Lest the ant should peep into the pit, discover its hideous form below, and then retreat, this ant-lion had actually the cunning to bury its body in the sand, leaving only a small portion of its head to be seen.
Both Doña Isidora and the little Leona remained watching with increased interest. They were very anxious to witness the result. They were not kept long in suspense. I have already stated that many ants were crawling about. There were dozens of them “quartering” the ground in every direction in search of their own prey; and they left not an inch of it unsearched. At last one was seen to approach the trap of the ant-lion. Curiosity brings it to the very edge of that terrible pit-fall. It protrudes its head and part of its body over the brink – it is not such a terrible gulf to look into – if it should slip down, it could easily crawl out again. Ha! it little knows the enemy that is ambushed there. It perceives something singular – an odd something – perhaps it might be something good to eat. It is half-resolved to slide down and make a closer examination of this something. It is balancing on the brink, and would, no doubt, have gone down voluntarily, but that is no longer left to its own choice. The mysterious object at the bottom of the funnel suddenly springs up and shows itself – it is the ant-lion in all its hideous proportions; and before the little ant can draw itself away, the other has flung around it a shower of sand that brings it rolling down the side of the pit. Then the sharp callipers are closed upon the victim – all the moisture in his body is sucked out – and his remains, now a dry and shapeless mass, are rested for a moment upon the head of the destroyer, and then jerked far outside the pit!
The ant-lion now dresses his trap, and, again burying himself in the sand, awaits another victim.
Doña Isidora and Leona had watched all the manoeuvres of the ant-lion with great interest, and Leona, after the bite she had had, was not in any mood to sympathise with the ants. Indeed, she felt rather grateful to the ant-lion, ugly as he was, for killing them.
Presently Leon returned from the woods, and was shown the trap in full operation; but Leon, upon this day, was full of adventures that had occurred upon the hills to himself, Guapo, and Don Pablo. In fact, he had hastened home before the others to tell his mamma of the odd incidents to which he had been a witness.
That morning they had discovered a new mancha of cinchona-trees. When proceeding towards them they came upon the dead carcass of a deer. It was a large species, the Cervus antisensis, but, as it had evidently been dead several days, it was swollen out to twice its original size, as is always the case with carcasses of animals left exposed in a warm climate. It was odd that some preying animals had not eaten it up. A clump of tall trees that shaded it, had, no doubt, concealed it from the sharp sight of the vultures, and these birds, contrary to what has so often been alleged, can find no dead body by the smell. Neither ants nor animals that prey upon carrion had chanced to come that way, and there lay the deer intact.
So thought Don Pablo and Leon. Guapo, however, was of a different opinion, and, going up to the body, he struck it a blow with his axe. To the surprise of the others, instead of the dead sound which they expected to hear, a dry crash followed the blow, and a dark hole appeared where a piece of thin shell-like substance had fallen off. Another blow from Guapo’s axe, and the whole side went in. Not a bit of carcass was there; there were bones – clean bones – and dry hard skin, but no flesh, not an atom of flesh!
“Tatou-poyou!” quietly remarked Guapo.
“What!” said Don Pablo, “an armadillo, you think?” recognising, in Guapo’s words, the Indian name for one of the large species of armadillos.
“Yes,” replied Guapo. “All eaten by the tatou-poyou. See! there’s his hole.”
Don Pablo and Leon bent over the sham carcass, and, sure enough, under where its body had been they could see a large hole in the ground. Outside the carcass, also, at the distance of several feet was another.
“That is where he entered,” said Guapo, pointing to the second. “He’s not about hero now,” continued he, “no, no, – ate all the meat, and gone long ago.”
This was evident, as the hollow skeleton was quite dry, and had evidently been empty for a good while.
Don Pablo was pleased at this incident, as it gave him an opportunity of verifying a curious habit of the armadillos. These creatures are among the finest burrowers in the world, and can bury themselves in the earth in a few seconds’ time; but, being badly toothed, – some of them altogether without teeth, – they can only feed upon very soft substances. Putrid flesh is with them a favourite “dish,” and in order to get at the softest side of a carcass, they burrow under, and enter it from below, rarely leaving their horrid cave until they have thoroughly cleared it out.
The bark-hunters now passed on, Don Pablo making many inquiries about the armadillos, and Guapo giving replies, while Leon listened with interest. Guapo knew a good deal about these curious creatures, for he had eaten many a dozen of them in his time, and as many different kinds of them too. Their feeding upon carrion had no effect on Guapo’s stomach, and, indeed, white people in South America relish them as much as Indians. The white people, however, make a distinction in the species, as they suppose some kinds to be more disposed to a vegetable diet than others. There are some in the neighbourhood of the settlements, that occasionally pay a visit to the graveyards or cemeteries, and these kinds do not go down well. All of them will devour almost any sort of trash that is soft and pulpy, and they are more destructive to the ant than even the ant-eaters themselves. How so? Because, instead of making a nice little hole in the side of the ant-hill, as the tamanoirs do, and through this hole eating the ants themselves, the armadillos break down a large part of the structure and devour the larva. Now the ants love these larva more than their own lives, and when these are destroyed, they yield themselves up to despair, refuse to patch up the building, the rain gets in, and the colony is ruined and breaks up.
It does not follow, however, that the flesh of the armadillo should be “queer” because the animal itself eats queer substances. Among carnivorous creatures the very opposite is sometimes the truth; and some animals – as the tapir, for instance – that feed exclusively on sweet and succulent vegetables, produce a most bitter flesh for themselves. About this there is no standing law either way.
The flesh of the armadillo is excellent eating, not unlike young pork, and, when “roasted in the shell” (the Indian mode of cooking it), it is quite equal, if not superior, to a baked “pig,” a dish very much eaten in our own country.
Guapo did not call them armadillos – he had several Indian names for different kinds of them. “Armadillo” is the Spanish name, and signifies the “little armed one,” the diminutive of “armado” or “armed.” This name is peculiarly appropriate to these animals, as the hard bony casing which covers the whole upper parts of their bodies, bears an exceeding resemblance to the suits of plate armour worn in the days of Cortez and chivalry.
On the head there is the helmet, the back is shielded by a corslet, and even the limbs are covered with greaves. Of course, this armour is arranged differently in the different species, and there is more or less hair upon all, between the joinings of the plates.
These points were not touched upon by Guapo, but others of equal interest were. He went on to say that he knew many different kinds of them; – some not bigger than a rat, and some as large as a full-grown sheep; some that were slow in their paces, and others that could outrun a man; some that were flat, and could squat so close as hardly to be seen against the ground, – (these were tatou-poyous, the sort that had hollowed out the deer); and some again that were high-backed and nearly globe-shaped. Such was Guapo’s account of these curious animals which are found only in the warmer regions of North and South America.
Conversing in this way, the bark-hunters, at length, reached the cinchona-trees, and then all talk about armadillos was at an end. They went lustily to their work – which was of more importance – and, under Guapo’s axe, several of the cinchonas soon “bit the dust.”
There was a spot of open ground just a little to one side of where these trees stood. They had noticed, on coming up, a flock of zamuros, or black vultures, out upon this ground, clustered around some object. It was the carcass of another deer. The first blow of the axe startled the birds, and they flapped a short way off. They soon returned, however, not being shy birds, but the contrary.
There was nothing in all this to create surprise, except, perhaps, the dead deer. What had been killing these animals? Not a beast of prey, for that would have devoured them, unless, indeed, it might be the puma, that often kills more than he can eat.
The thought had occurred to Don Pablo that they might have died from the poisoned arrows of an Indian. This thought somewhat disquieted him, for he knew not what kind of Indians they might be, – they might be friendly or hostile; – if the latter, not only would all his plans be frustrated, but the lives of himself and party would be in danger. Guapo could not assure him on this head; he had been so long absent from the Great Montaña that he was ignorant of the places where the tribes of these parts might now be located. These tribes often change their homes. He knew that the Chunchos sometimes roamed so far up, and they were the most dangerous of all the Indians of the Montaña, – haters of the whites, fierce and revengeful. It was they who several times destroyed the settlements and mission stations. If Chunchos were in the woods they might look out for trouble. Guapo did not think there were any Indians near. He would have seen some traces of them before now, and he had observed none since their arrival. This assurance of the knowing Indian quite restored Don Pablo’s confidence, and they talked no longer on the subject. After a while, their attention was again called to the vultures. These filthy creatures had returned to the deer, and were busily gorging themselves, when, all at once, they were seen to rise up as if affrighted. They did not fly far, – only a few feet, – and stood with outstretched necks looking towards the carrion, as if whatever had frightened them was there.
The bark-hunters could perceive nothing. It was the body of a small deer, already half eaten, and no object bigger than a man’s hand could have been concealed behind it. The zamuros, however, had seen something strange – else they would hardly have acted as they did – and, with this conviction, the bark-hunters stopped their work to observe them.
After a while the birds seemed to take fresh courage, hopped back to the carrion, and recommenced tearing at it. In another moment they again started and flew back, but, this time, not so far as before, and then they all returned again, and, after feeding another short while, started back a third time.
This was all very mysterious, but Guapo, guessing what was the matter, solved the mystery by crying out —
“Tatou-poyou!”
“Where?” inquired Don Pablo.
“Yonder, master, – yonder in the body of the beast.”
Don Pablo looked, and, sure enough, he could see something moving; it was the head and shoulders of an armadillo. It had burrowed and come up through the body of the deer, thus meeting the vultures half-way! No doubt, it was the mysterious mode by which it had entered on the stage that had frightened them.
They soon, however, got over their affright, and returned to their repast.
The armadillo – a very large one – had, by this time, crept out into the open air, and went on eating.
For a while the zamuros took no heed of him, deeming, perhaps, that, although he had come in by the back-door, he might have as good a right upon the premises as themselves. Their pacific attitude, however, was but of short duration; something occurred to ruffle their temper – some silent affront, no doubt, – for the bark-hunters heard nothing. Perhaps the tatou had run against the legs of one, and scraped it with the sharp edge of his corslet. Whether this was the cause or no, a scuffle commenced, and the beast in armour was attacked by all the vultures at once.
Of course he did not attack in turn, he had no means; he acted altogether on the defensive; and this he was enabled to do by simply drawing in his legs and flattening himself upon the ground. He was then proof, not only against the beaks and weak talons of a vulture, but he might have defied the royal eagle himself.
After flapping him with their wings, and pecking him with their filthy beaks, and clawing him with their talons, the zamuros saw it was all to no purpose, and desisted. If they could not damage him, however, they could prevent him from eating any more of the deer; for the moment he stretched out his neck, several vultures sprang at him afresh, and would have wounded him in the tender parts of his throat had he not quickly drawn in his head again. Seeing that his feast was at an end – at least above ground, – he suddenly raised his hind-quarters, and in a brace of seconds buried himself in the earth. The vultures pecked him behind as he disappeared, but the odd manner of his exit, like that of his entrée, seemed to mystify them, and several of them stood for some moments in neck-stretched wonder.
This scene had scarcely ended when a pair of fresh armadillos were espied, coming from the farther edge of the opening, and, in fact, from the edge of a precipice, for the river flowed close by, and its channel was at that point shut in by cliffs. These two were large fellows, and were making speedily towards the carrion, in order to get up before it was all gone. Guapo could stand it no longer Guapo had tasted roast armadillo, and longed for more. In an instant, therefore, axe in hand, he was off to intercept the new comers. Don Pablo and Leon followed to see the sport and assist in the capture.
The armadillos, although not afraid of the vultures, seeing the hunters approach, turned tail and made for the precipice. Guapo took after one, while Don Pablo and Leon pursued the other. Guapo soon overhauled his one, but, before he could lay his hands upon it, it had already half buried itself in the dry ground. Guapo, however, seized the tail and held on; and, although not able to drag it out, he was resolved it should get no deeper.
The one pursued by Don Pablo had got close to the edge of the precipice, before either he or Leon could come up with it. There it stood for a moment, as if in doubt what plan to pursue. Don Pablo and Leon were congratulating themselves that they had fairly “cornered” it, for the cliff was a clear fall of fifty feet, and, of course, it could get no farther in that direction, while they approached it from two sides so as to cut off its retreat. They approached it with caution, as they were now near the edge, and it would not do to move too rashly. Both were bent forward with their arms outstretched to clutch their prey; they felt confident it was already in their grasp. Judge their astonishment, then, at seeing the creature suddenly clew itself into a round ball, and roll over the cliff!
They looked below. They saw it upon the ground; they saw it open out again, apparently unharmed, for, the next moment, it scuttled off and hid itself among the rocks by the edge of the water!
They turned toward Guapo, who was still holding his one by the tail, and calling for help. Although it was but half buried, all three of them could not have dragged it forth by the tail. That member would have pulled out before the animal could have been dislodged; and such is not an unfrequent occurrence to the hunters of the armadillo. Don Pablo, however, took hold of the tail and held fast until Guapo loosened the earth with his axe, and then the creature was more easily “extracted.” A blow on its head from Guapo made all right, and it was afterwards carried safely to the house, and “roasted in the shell.”
That was a great day among the “armadillos.”
