Even so with the Epeira’s work.  The Spider’s front tarsi are the motor; the revolving spool is the captured insect; the steel eyelet is the aperture of the spinnerets.  To bind the subject with precision and dispatch nothing could be better than this inexpensive and highly-effective method.

Less frequently, a second process is employed.  With a quick movement, the Spider herself turns round about the motionless insect, crossing the web first at the top and then at the bottom and gradually placing the fastenings of her line.  The great elasticity of the lime-threads allows the Epeira to fling herself time after time right into the web and to pass through it without damaging the net.

Let us now suppose the case of some dangerous game:  a Praying Mantis, for instance, brandishing her lethal limbs, each hooked and fitted with a double saw; an angry Hornet, darting her awful sting; a sturdy Beetle, invincible under his horny armour.  These are exceptional morsels, hardly ever known to the Epeirae.  Will they be accepted, if supplied by my stratagems?

They are, but not without caution.  The game is seen to be perilous of approach and the Spider turns her back upon it, instead of facing it; she trains her rope-cannon upon it.  Quickly, the hind-legs draw from the spinnerets something much better than single cords.  The whole silk-battery works at one and the same time, firing a regular volley of ribbons and sheets, which a wide movement of the legs spreads fan-wise and flings over the entangled prisoner.  Guarding against sudden starts, the Epeira casts her armfuls of bands on the front-and hind-parts, over the legs and over the wings, here, there and everywhere, extravagantly.  The most fiery prey is promptly mastered under this avalanche.  In vain, the Mantis tries to open her saw-toothed arm-guards; in vain, the Hornet makes play with her dagger; in vain, the Beetle stiffens his legs and arches his back:  a fresh wave of threads swoops down and paralyses every effort.

These lavished, far-flung ribbons threaten to exhaust the factory; it would be much more economical to resort to the method of the spool; but, to turn the machine, the Spider would have to go up to it and work it with her leg.  This is too risky; and hence the continuous spray of silk, at a safe distance.  When all is used up, there is more to come.

Still, the Epeira seems concerned at this excessive outlay.  When circumstances permit, she gladly returns to the mechanism of the revolving spool.  I saw her practise this abrupt change of tactics on a big Beetle, with a smooth, plump body, which lent itself admirably to the rotary process.  After depriving the beast of all power of movement, she went up to it and turned her corpulent victim as she would have done with a medium-sized Moth.

But with the Praying Mantis, sticking out her long legs and her spreading wings, rotation is no longer feasible.  Then, until the quarry is thoroughly subdued, the spray of bandages goes on continuously, even to the point of drying up the silk-glands.  A capture of this kind is ruinous.  It is true that, except when I interfered, I have never seen the Spider tackle that formidable provender.
