Confessions of a Beachcomber by Edmund James Banfield (funny books to read TXT) 📕

ants, grey ants, green ants; ants large, ants small; ants slothful, ants brisk; meat-eating ants, grain-eating ants, fruit-eating ants, nectar-imbibing ants; ants that fight, ants that run away; ants that live under coldest stone, ants that dwell among the treetops; silent ants, ants that literally "kick up" a row; good ants, bad ants, ants that are merely so so--we have them all and would not part with any--not even the stinging green ants, which are among the most singular of the tribe, nor even the "white ant" (which is not an ant), that would literally eat us out of house and home if not rigorously excluded and warred against with poison, for they are the great scavengers of woodeny debris.

Green ants do disfigure orange and mango trees with their "nests," and they have the temper of furies; but they wage war on many of the insects which bother plants, and clear away insect carrion, and carrion, in fact, of all sorts. This ant, to which has been given the official title of "emerald-coloured leaf dweller," constructs a pocket with leaves of living trees (and, very rarely, of the blades of living grass), and dwelling therein establishes populous colonies. The queen or mother ant sets up her separate establishment by curling a small leaf or the corner of a large one, joining the edges with a white cottony fabric, and forthwith begins to raise a family. She is a portly creature--unlike her slim, semi-transparent workers and warriors--and most prolific, and her family increases marvellously. As it multiplies, ingenious additions of living leaves are made to the pocket or purse, until it may assume the size of a football and be the home of millions of alert, pugnacious, inquisitive, foraging insects, whose bites are dreaded by individuals whose skin is extra sensitive.

Is it not astonishing that insects, possessing even in combination such trivial muscular power as the green tree-ant, should be able to cause leaves 12 inches long by 8 inches wide to curl up so that the apex shall almost touch the base, or that the parallel borders shall be brought together with the nicest apposition? The astonishment increases when it is recognised that at the founding of a colony there are but few workers to co-operate in the undertaking.

The minute caterpillar of a certain species of moth mines leaves, and eating away the cellular structures, causes them to twist irregularly, and eventually spins on the spot a cocoon of green silk in which it undergoes metamorphosis. A local caterpillar, too, converts the tough harsh leaves of a fig-tree (FICUS FASCICULATA) into a close and perfect scroll by an elaborate system of haulage, spinning silken strands as required, having primarily rendered the leaf the more easy to manipulate by nibbling away a portion of the midrib. In this scroll the insect dozes until in process of time it is transformed, and emerges a bright but short-lived butterfly.

But, as far as my personal observation goes, the green tree-ants do not effect any alteration in the superficial appearance nor destroy the structure of leaves, nor employ any physical power at the first stages of the construction of a habitation. The process by which a leaf is curled extends over several days, and but few take part in it. Half a dozen ants may be seen perpetually engaged in, apparently, an unmethodical but extremely minute and critical inspection of the rhachis and the nerves or ribs of the leaf. Days pass. The ants are there all the time, examining the leaf and communicating with each other whensoever they meet. Imperceptibly the leaf begins to curl. The ants continue to make mesmeric passes over the nerves with ever-waving antennae.

In accordance with the will and the design of the architects, who merely stand by and gesticulate, the opposite margins approach, or the apex curls towards the base, or towards one of the sides to form a miniature funnel. When the extremities are so close that the intervening space may be spanned, threads of white gossamer are laced across, and the slack being taken up by degrees, in a few days a cosy pocket with closely-fitting seams is completed.

How is this folding of the leaf accomplished? A theory which presents itself is that the ants eject some active chemical principle into certain of the cells of the leaf tissue, and that the stimulus is transmitted by excitation from cell to cell, bringing about a general and uniform contraction without destroying the vitality of the leaf. Further, by the application of the injection to specific cells the ants convey impulses to specific nerves, causing the leaf to curl longitudinally or laterally, or at any angle they design. The poison that a single ant injects into the neck of a brawny man so affects his nervous system that he twists and writhes and stamps his feet with energy sufficient to destroy millions of the species. Maybe a slightly different compound is reserved for vegetable substances, which can offer only a flabby sort of remonstrance. If this theory be supported on investigation, surely the green tree-ant will deserve to be catalogued among creatures who have solved labour-saving problems--who employ consciousness, if not rational thought, to compensate for physical frailty. This theory is applicable to the manipulation of a single leaf only, and of a leaf of considerable size. Yet these feeble folk more frequently take up their quarters in trees bearing small leaves, of which scores are embodied in a mansion. Immense and concentrated exertion is necessary to draw far-flung branchlets and leaves together, and the feverish host accomplishes a seemingly impossible feat by an organised combination of engineering with co-operative labour. Spaces between leaves and twigs four and five inches wide are bridged by chains of ants--each individual clasping with its mandibles above the abdominal segment its immediate companion; occasionally the ant grips its fellow by the posterior legs, and is so held by the next in order. In the construction of these chains ants hastily mass at each side of the gulf to be spanned, and crawling, or rather running over each other, form pendant strands, each ant a living link. The chains sway until the terminal links engage, when they are immediately shortened up. Several of these chains are swung across parallel to each other with astonishing rapidity; and in addition to the constant strain of the hauling workers at each end they are used as bridges by innumerable other workers and fussy superintendents, the traffic on them being almost as voluminous and bustling as that of a Thames thoroughfare. Gradually the most obstinate branchlet with its spray of leaves is drawn into juxtaposition with the main part of the mansion. Then the living spans become more numerous, presenting the appearance of great stitches. As the edges of the leaves are brought together they are fastened with white gossamer while the tireless workers strain themselves, heroically holding the edges in apposition. The gossamer seems to be obtained in part from the pupuae, which, borne in the mandibles of workers, are passed to and fro as weavers' shuttles. As a rule, insects which house themselves in leaves are vegetarian, but the green ant is demonstratively carnivorous, using leaves solely for shelter.

An aboriginal--to repeat perhaps a needless observation--regards the most of things of this earth from a dietetic standpoint. He does not so regard the green tree-ant in vain. He knows when the pocket is packed with white larvae and white helpless infant ants, or with helpless green ones big of abdomen, and consenting to the assaults of the adults, cuts away the supporting branch and shakes off the furious citizens, or expels them with the smoke and fire of paper-bark torches, or, maybe, casts the pocket into water so that the adult ants may swim ashore, abandoning those that cannot, on account of immaturity or incompetence, to their fate.

Eaten raw, the larvae are pungent morsels, or macerated in water in company with relatives distended to the degree of helplessness, form a cordial that is sharp to the palate, scarifying to the throat, and consoling to the stomach replete with the cold and sodden foods with which blacks often have to be content.

Tetchy and quarrelsome, staccato in action, the warriors of a colony bury their forceps in the skin and stand upon their heads to give all their weight to the attack; but each individual retains its grip until squashed and crumpled up, and the human being who has suffered the assault comments on it in language corresponding with the sensitiveness or otherwise of his skin. Consequently the green tree-ant is not as a rule regarded with any tenderness or consideration, and there never existed a green ant which hesitated to attack the greatest man. He is quite as heroic as a bee--though armed much less efficiently--and far more resentful.

A brilliant black ant imitates its green cousin in the construction of a leafy dwelling somewhat similar in design but on a smaller scale, and having no apparent weapon of defence, save odour--and not very much of that--adopts a novel plan of protecting its refuge against assaults. However gently the leafy house is touched the denizens set up a violent agitation, the simultaneous efforts of hundreds making a sound quite loud enough to scare away intruders whose senses are attuned to the silence and rustlings of the jungle. The noise, which resembles that which results from the easy agitation of coarse sand in a crisp paper envelope, seems to be caused by the ants kicking or drumming on the sides and partitions of the house, the partitions being composed of a light brown fabric, tense, tough and resonant.



WOOING WITH WINGS

Among the many engaging scenes and frolics that are ever taking place along the flounces of the jungle, where the serrated leaves of the fern of God make living lacework up and among the tangle of foliage, none is prettier than the love flight of the green and gold butterfly (ORNITHOPTERA CASSANDRA). Human beings, who in their marriage ceremonies array themselves to the best advantage and assume their most charming traits, can hardly withhold attention from other and more ethereal creatures when they become subject to the divine passion. All have their moments of bliss, and the butterfly--"the embodiment of pure felicity --happy in what it has and happier still in searching for something else"--reveals its "love-sickness and pain" as the bloom of its gay and sportful existence.

In the courtship of this particular species the male exercises a singular fascination, while the female gracefully and without hesitation submits to the spell. He has flitted airily in the sunshine, glorying in a livery of green and gold and black, has daintily sipped nectar from the scarlet hibiscus flowers, has soared over the highest bloodwood in wild but idle impulse, and in a flash, is fervently in love. Judged by appearance alone he has chosen quite an unworthy bride. She is much the larger, darker and heavier, and has little of the colouring of her passionate wooer on her wings, though her body is decorated with unexpected red. Her flight, ordinarily, is cumbersome and slow, and her demeanour pensive--almost prim. She seems to be of a steady, matronly disposition, whereas the shape of the wings of her mate alone denotes quite a different ideal of life. He is all alert, charged to the full with nervous energy--free, careless, inconsequent, but absolutely irresistible.

When the pair meet, what time the fancies of butterflies lightly turn to thoughts of love, he swoops impetuously towards her and rises in a graceful curve, seeming to enchant her with the display of his colours. She forthwith amends her staid behaviour, and begins a quivering, fluttering flight, rising and falling with gentle, rhythmical grace. He, hovering about with rapid wing movements, harmoniously responds to her undulations. Still maintaining her
