CURIOSITIES RESPECTING INSECTS.

To their delicious task the fervent bees, In swarming millions, tend; around, athwart, Through the soft air the busy nations fly, Cling to the bud, and with inserted tube Suck its pure essence, its ethereal soul; And oft, with bolder wing, they, soaring, dare The purple heath, or where the wild thyme grow, And yellow load them with the luscious spoil. Thomson. What various wonders may observers see In a small insect—the sagacious bee! Mark how the little untaught builders square Their rooms, and in the dark their lodgings rear; Nature’s mechanics, they unwearied strive And fill, with curious labyrinths, the hive. See what bold strokes of architecture shine Through the whole frame, what beauty, what design! Blackmore.

The Honey Bee.

This important insect has been long and justly celebrated for its wonderful polity, the neatness and precision with which it constructs its cells, and the diligence with which it provides, during the warmth of summer, a supply of food for the support of the hive during the rigours of the succeeding winter. The general history of this interesting insect has been amply detailed by various authors, as Swammerdam, Reaumur, &c. &c. Among the most elaborate accounts of later times, may be mentioned that of Mr. John Hunter, which made its appearance in the Philosophical Transactions for the year 1792; and that of M. Huber, contained in his Nouvelles Observations sur les Abeilles, addressed to M. Bonnet, the celebrated author of the “Contemplations de la Nature.” The following account is drawn principally from Hunter and Huber.

There are three periods, observes Hunter, at which the history of the bee may commence: first, in the spring, when the queen begins to lay her eggs; in the summer, at the commencement of a new colony; or in the autumn, when they go into winter-quarters. We shall begin the particular history of the bee with the new colony, when nothing is formed. When a hive sends off a colony, it is commonly in the month of June; but that will vary according to the season, for, in a mild spring, bees sometimes swarm in the middle of May, and very often at the latter end of it. Before they come off, they commonly hang about the mouth of the hole or door of the hive for some days, as if they had not sufficient room within for such hot weather, which we believe is very much the case; for if cold or wet weather come on, they stow themselves very well, and wait for fine weather. But swarming appears to be rather an operation arising from necessity; for they do not seem to remove voluntarily, because if they have an empty space to fill, they do not swarm; therefore, by increasing the size of the hive, the swarming is prevented. This period is much longer in some than in others. For some evenings before they come off, is often heard a singular noise, a kind of ring, or sound of a small trumpet; by comparing it with the notes of a piano-forte, it seemed to be the same sound with the lower A of the treble. The swarm commonly consists of three classes; a female or females, males, and those commonly called mules, which are supposed to be of no sex, and are the labourers; the whole, about two quarts in bulk, making about six or seven thousand. It is a question that cannot easily be determined, whether this old stock sends off only young of the same season, and whether the whole of their young ones, or only a part.

As the males are entirely bred in the same season, part go off; but part must stay, and most probably it is so with the others. They commonly come off in the heat of the day, often immediately after a shower. When one goes off, they all immediately follow, and fly about, seemingly in great confusion, although there is one principle actuating the whole. They soon appear to be directed to some fixed place; such as the branch of a tree or bush, the cavities of old trees, or holes of houses leading into some hollow place; and whenever the stand is made, they immediately repair to it till they are all collected. But it would seem, in some cases, that they had not fixed upon any resting-place before they come off, or, if they had, that they were either disturbed, if it was near, or that it was at a great distance; for, after hovering some time, as if undetermined, they fly away, mount up into the air, and go off with great velocity. When they have fixed upon their future habitation, they immediately begin to make their combs for they have the materials within themselves. “I have reason,” says Mr. Hunter, “to believe that they fill their crops with honey when they come away, probably from the stock in the hive. I killed several of those that came away, and found their crops full, while those that remained in the hive had their crops not near so full: some of them came away with farina on their legs, which I conceive to be rather accidental. I may just observe here, that a hive commonly sends off two, sometimes three swarms in a summer, but that the second is commonly less than the first, and the third less than the second; and this last has seldom time to provide for the winter.

“The materials of their dwelling or comb, which is the wax, is the next consideration, with the mode of forming, preparing, or disposing of it. In giving a totally new account of the wax, I shall first shew it can hardly be what it has been supposed to be. First, I shall observe that the materials, as they are found composing the comb, are not to be found in the same state (as a composition) in any vegetable, where they have been supposed to be got. The substance brought in on the legs, which is the farina of the flowers of plants, is, in common, I believe, imagined to be the materials of which the wax is made, for it is called by most, the wax: but it is the farina, for it is always of the same colour as the farina of the flower where they are gathering; and, indeed, we see them gathering it, and we also see them covered almost all over with it like a dust: nevertheless, it has been supposed to be the wax, or that the wax was extracted from it. Reaumur is of this opinion.

“I made several experiments, to see if there was such a quantity of oil in it, as would account for the quantity of wax to be formed, and to learn if it was composed of oil. I held it near the candle; it burnt, but did not smell like wax, and had the same smell when burning, as farina when it was burnt. I observed, that this substance was of different colours on different bees, but always of the same colour on both legs of the same bee; whereas a new-made comb was all of one colour. I observed, that it was gathered with more avidity for old hives, where the comb is complete, than for those hives where it was only begun, which we could hardly conceive, admitting it to be the materials of wax. Also we may observe, that at the very beginning of a hive, the bees seldom bring in any substance on their legs for two or three days, and after that, the farina gatherers begin to increase; for now some cells are formed to hold it as a store, and some eggs are laid, which, when hatched, will require this substance as food, and which will be ready when the weather is wet.

“The wax is formed by the bees themselves; it may be called an external secretion of oil, and I have found that it is formed between each scale of the under side of the belly. When I first observed this substance, in my examination of the working bee, I was at a loss to say what it was: I asked myself if it were scales forming, and whether they cast the old, as the lobster, &c. does? but it was to be found only between the scales on the lower side of the belly. On examining the bees through glass hives, while they were climbing up the glass, I could see that most of them had this substance, for it looked as if the lower or posterior edge of the scale was double, or that there were double scales; but I perceived it was loose, not attached. Finding that the substance brought in on their legs was farina, intended, as appeared from every circumstance, to be the food of the bee, and not to make wax; and not having yet perceived any thing that could give me the least idea of wax; I conceived these scales might be it, at least I thought it necessary to investigate them. I therefore took several on the point of a needle, and held them to a candle, where they melted, and immediately formed themselves into round globules; upon which I no longer doubted that this was the wax, which opinion was confirmed to me by not finding those scales but in the building season.
