The exit of the family is performed in a single group and, this time, before the moult, perhaps for lack of the space necessary for the delicate casting of the skin. The conical bag falls far short of the balloon in size; those packed within would sprain their legs in extracting them from their sheaths. The family, therefore, emerges in a body and settles on a sprig hard by.
This is a temporary camping-ground, where, spinning in unison, the youngsters soon weave an open-work tent, the abode of a week, or thereabouts. The moult is effected in this lounge of intersecting threads. The sloughed skins form a heap at the bottom of the dwelling; on the trapezes above, the flaylings take exercise and gain strength and vigour. Finally, when maturity is attained, they set out, now these, now those, little by little and always cautiously. There are no audacious flights on the thready airship; the journey is accomplished by modest stages.
Hanging to her thread, the Spider lets herself drop straight down, to a depth of nine or ten inches. A breath of air sets her swinging like a pendulum, sometimes drives her against a neighbouring branch. This is a step towards the dispersal. At the point reached, there is a fresh fall, followed by a fresh pendulous swing that lands her a little farther afield. Thus, in short tacks, for the thread is never very long, does the Spiderling go about, seeing the country, until she comes to a place that suits her. Should the wind blow at all hard, the voyage is cut short: the cable of the pendulum breaks and the beastie is carried for some distance on its cord.
To sum up, although, on the whole, the tactics of the exodus remain much the same, the two spinstresses of my region best-versed in the art of weaving mothers’ wallets failed to come up to my expectations. I went to the trouble of rearing them, with disappointing results. Where shall I find again the wonderful spectacle which the Cross Spider offered me by chance? I shall find it—in an even more striking fashion—among humbler Spiders, whom I had neglected to observe.
CHAPTER VIII: THE CRAB SPIDER
The Spider that showed me the exodus in all its magnificence is known officially as Thomisus onustus, WALCK. Though the name suggest nothing to the reader’s mind, it has the advantage, at any rate, of hurting neither the throat nor the ear, as is too often the case with scientific nomenclature, which sounds more like sneezing than articulate speech. Since it is the rule to dignify plants and animals with a Latin label, let us at least respect the euphony of the classics and refrain from harsh splutters which spit out a name instead of pronouncing it.
What will posterity do in face of the rising tide of a barbarous vocabulary which, under the pretence of progress, stifles real knowledge? It will relegate the whole business to the quagmire of oblivion. But what will never disappear is the popular name, which sounds well, is picturesque and conveys some sort of information. Such is the term Crab Spider, applied by the ancients to the group to which the Thomisus belongs, a pretty accurate term, for, in this case, there is an evident analogy between the Spider and the Crustacean.
Like the Crab, the Thomisus walks sideways; she also has forelegs stronger than her hind-legs. The only thing wanting to complete the resemblance is the front pair of stone gauntlets, raised in the attitude of self-defence.
The Spider with the Crab-like figure does not know how to manufacture nets for catching game. Without springs or snares, she lies in ambush, among the flowers, and awaits the arrival of the quarry, which she kills by administering a scientific stab in the neck. The Thomisus, in particular, the subject of this chapter, is passionately addicted to the pursuit of the Domestic Bee. I have described the contests between the victim and her executioner, at greater length, elsewhere.
The Bee appears, seeking no quarrel, intent upon plunder. She tests the flowers with her tongue; she selects a spot that will yield a good return. Soon she is wrapped up in her harvesting. While she is filling her baskets and distending her crop, the Thomisus, that bandit lurking under cover of the flowers, issues from her hiding-place, creeps round behind the bustling insect, steals up close and, with a sudden rush, nabs her in the nape of the neck. In vain, the Bee protests and darts her sting at random; the assailant does not let go.
