THE EARWIG

Baron de Geer, a famous Swedish naturalist, gives us the following: "About the end of March I found an earwig brooding over her eggs in a small cell, scooped out in a garden border. In order to watch her proceedings, I removed the eggs into my study, placing them upon fresh earth under a bell-glass. The careful mother soon scooped out a fresh cell, and collected the scattered eggs with great care to the little nest, placing herself over them, to prevent the too rapid evaporation of the moisture. When the earth began to dry up, she dug the cell gradually deeper, till at length she got almost out of view. At last, the cell became too dry, and she removed the eggs to the edge of the glass, where some of the moisture had condensed. Upon observing this, I dropped some water into the abandoned cell, and the mother soon after removed the eggs there. Her subsequent proceedings were no less interesting; but I regret to add that, during my absence, the bell-glass was removed, and the earwig escaped with her eggs."

THE CRICKET

Mr. Southey describes the perilous situation of a ship sailing to Brazil, which was saved from shipwreck by the singing of a ground cricket. "Three days they stood towards land. A soldier, who had set out in ill health, had brought a ground cricket with him from Cadiz, thinking to be amused by the insect's voice; but it had been silent the whole distance, to his no small disappointment. Now, on the fourth morning, the grillo had begun to ring its shrill rattle, scenting the land. Such was the miserable watch that had been kept, that, upon looking out at this warning, they perceived high rocks within bowshot, against which, had it not been for the insect, they must inevitably have been lost. They had just time to drop anchor. From hence they coasted along, the grillo singing every night as if it had been on shore, till they reached the Islands of St. Catalina."

In China, the people take as much pleasure in cricket fights as the Spaniards do in bull fights. Two crickets are pitted against each other, and crowds of people gather round, to witness the combat. The insects rush at each other with great fury; and the spectators, high and low, rich and poor, seem to experience the most lively sensations of delight.

THE LOCUST

In July, 1827, the Russian General Cobley had a grand battle with the locusts, on his estate of Coblewka, along the borders of the Sea of Oschakoff. The locusts were marching in twenty-four columns, and were destroying all the crops. General Cobley collected the peasants on his estate, and from all the neighboring country, amounting to five hundred persons. They were armed with pitchforks, spades, drums, and bells; and, thus equipped, they commenced their march against the invaders. They soon compelled them to retreat, and pursued them incessantly towards the sea, where they were forced to jump into the water, and were drowned. Three days afterwards, the sea-shore was covered with the dead locusts, cast up by the waves; the air was infected by a fetid exhalation, and great numbers of poisoned fish were cast up by the waves on the strand. It is probable that the fish had fed on the locusts.

THE ANT

Anecdotes.– In tracing the designs of the cells and galleries, each ant appears to follow its own fancy. A want of accordance must therefore frequently take place at the point where their works join; but they never appear to be embarrassed by any difficulties of this kind. An instance is related, in which two opposite walls were made, of such different elevations, that the ceiling of the one, if continued, would not have reached above half way of the height of the other. An experienced ant, arriving at the spot, seemed struck with the defect, immediately destroyed the lower ceiling, built up the wall to the proper height, and formed a new ceiling with the materials of the former.

In the "Transactions of the French Academy," an account is given of an ant, that was taken from a hill, and thrown upon a heap of corn. It seemed attentively to survey this treasure, and then hastened back to its former abode, where it communicated intelligence of the land of plenty; for an immense host of its brethren quickly made their appearance, and commenced carrying off the grain.

M. Homberg informs us that, in Surinam, there is a species of ant called by the natives the visiting ant. These animals march in large troops, with the same order and precision as do a regularly-constituted army. They are welcome visitors to the natives, on account of their power of exterminating rats, mice, and other noxious animals, with which that country abounds. No sooner do they appear, than all the coffers, chests of drawers, and locked-up places in the house, are thrown open for them, when they immediately commence their work of destruction of animal life, as if commissioned by nature for that purpose. The only regret of the natives is, that they pay their visits but once in three or four years.

Two ants meeting on a path across a gravel-walk, one going to and the other from the nest, stop, touch each other's antennæ, and appear to hold a conversation. One would almost fancy that one was communicating to the other the best place for foraging.

THE CATERPILLAR

A curious species of manufacture was contrived by an officer of engineers residing at Munich. It consisted of lace veils, with open patterns on them, made entirely by caterpillars. Having made a paste of the leaves of the plant on which the insect feeds, he spread it thinly over a stone, or other flat substance, of the required size. He then, with a camel's hair pencil dipped in olive oil, drew a pattern he wished the insects to leave open. This stone was then placed in an inclined position, and a number of caterpillars were placed at the bottom. A peculiar species was chosen, which spins a strong web, and the animals commenced at the bottom, eating and spinning their way up to the top, carefully avoiding every part touched by the oil, but devouring every other part of the paste. The extreme lightness of these veils, combined with their strength, is surprising.

THE BUTTERFLY

In June, 1826, a column of butterflies, from ten to fifteen feet broad, was seen to pass over Neufchatel, in Switzerland; the passage lasted upwards of two hours, without any interruption, from the moment when the insects were observed.

THE MOTH

A moth was once caught, at Arracan, which measured ten inches from the tip of one wing to the tip of the other, both being variegated with the brightest colors.

THE SILKWORM

The great care bestowed upon this creature in China is shown in the following extract from an old work: "The place where their habitation is built must be retired, free from noisome smells, cattle, and all noises; as a noisome smell, or the least fright, makes great impressions upon so tender a breed; even the barking of dogs, and the crowing of cocks are capable of putting them in disorder when they are newly hatched. For the purpose of paying them every attention, an affectionate mother is provided for their wants; she is called Isan-more, mother of the worms. She takes possession of the chamber, but not till she has washed herself, and put on clean clothes which have not the least ill smell; she must not have eaten any thing before, or have handled any wild succory, the smell of which is very prejudicial; she must be clothed in a plain habit without any lining, that she may be more sensible of the warmth of the place, and accordingly increase or lessen the fire; but she must carefully avoid making a smoke, or raising a dust, which would be very offensive to these tender creatures, which must be carefully tended before the first time of casting their slough."

During the first twenty-four hours of the silkworm's existence, the patient Chinese feeds the objects of her care forty-eight times a day; during the second or third day, thirty times; and so on, reducing the number of meals as the worm grows older.

FLIES

Sir Arthur Young thus speaks of flies in his "Travels through the South of Europe: " "Flies form the most disagreeable circumstance in the southern climates. They are the first torments in Spain, Italy, and the olive districts of France. It is not that they bite, sting, or hurt; but they buzz, tease, and worry: your mouth, eyes, ears, and nose, are full of them; they swarm on every eatable. Fruit, sugar, milk, every thing, is attacked by them in such myriads, that if they were not driven away, by a person who has nothing else to do, to eat a meal is impossible. If I farmed in these countries, I think I should manure four or five acres of land a year with dead flies."

CLASS RADIATA … RADIATED ANIMALS

This class embraces those beings which are the lowest in the animal kingdom – those which have the fewest and most imperfect senses. Indeed, some of them so far resemble plants as to make the point of separation between the animal and vegetable kingdoms almost a matter of uncertainty. They are called radiata, because in most of them an arrangement may be traced, in their formation, like that of rays branching out from a centre. Among the creatures of this class are the star-fish, polypus, sea-anemone, and infusoria.

POLYPI

Captain Basil Hall makes some interesting remarks on the examination of a coral-reef, which is the product of the marine polypi. He observes that, during the different stages of the tide, the changes it undergoes are truly surprising. When the tide has left it for some time, it becomes dry, and appears to be a compact rock, exceedingly hard and rugged; but as the tide rises, and the waves begin to wash over it, the coral worms protrude themselves from holes which before were invisible. These animals are of a great variety of shapes and size, and in such prodigious numbers, that, in a short time, the whole surface of the rock appears to be alive and in motion. The most common worm is in the shape of a star, with arms from four to six inches long, which move in every direction to catch food. Others are so sluggish that they may be taken for pieces of rock, and are of a dark color; others are of a blue or yellow color; while some resemble a lobster in shape.

The Green Polype, or hydra, is found in clear waters, and may generally be seen in great plenty in small ditches and trenches of fields, especially in the months of April and May. It affixes itself to the under parts of leaves, and to the stalks of such vegetables as happen to grow immersed in the same water. The animal consists of a long, tubular body, the head of which is furnished with eight, and sometimes ten long arms, or tentacula, that surround the mouth.

It is of an extremely predacious nature, and feeds on the various species of small worms, and other water animals, that happen to approach. When any animal of this kind passes near the polype, it suddenly catches it with its arms, and, dragging it to its mouth, swallows it by degrees, much in the same manner as a snake swallows a frog. Two of them may sometimes be seen in the act of seizing the same worm at different ends, and dragging it in opposite directions with great force.

When the mouths of both are thus joined together upon one common prey, the largest polype gapes and swallows his antagonist; but, what is more wonderful, the animal thus swallowed seems to be rather a gainer by the misfortune. After it has lain in the conqueror's body for about an hour, it issues unhurt, and often in possession of the prey that had been the original cause of contention. The remains of the animals on which the polype feeds are evacuated at the mouth the only opening in the body. It is capable of swallowing a worm of thrice its own size: this circumstance, though it may appear incredible, is easily understood, when we consider that the body of the polype is extremely extensile, and is dilated, on such occasions, to a surprising degree.

This species are multiplied, for the most part, by a process resembling vegetation – one or two, or even more young ones emerging gradually from the sides of the parent animal; and these young are frequently again prolific before they drop off; so that it is no uncommon thing to see two or three generations at once on the same polype.
