Spiders like that were found within the tropics shortly subsequently. Travelers told us: birds get confused in their spider internet! The cork helmet can suspend on that - and it doesn't rush! thus robust ar the spider web threads. And one spider simply pulls out 3 or four kilometers of such threads for a month.
These wonderful spiders are referred to as nephiles. Nature has not stingy neither on paints, nor on the skills necessary for weavers, and liberally gave them to Nephilas.
The spider of Madagascar's nephilas, with golden breasts and fiery red legs in black "socks", sparks a sparkling gold internet. immense (with her toe and toe), sort of a large queen, rests on a carpet plain-woven of golden "wool" encircled by unpleasant dwarf males (the feminine weighs 5 grams, and her husband - thousand times less - 4-7 milligrams!).
Our national, the notable Miklukho-Maclay, was the primary European to ascertain and describe the terribly helpful use of the online by individuals in Papua. it's thus uncommon that stories concerning it several met with nice disbelief. 1 / 4 of a century when the death of Miklouho-Maclay, the collector of British repository of explanation A. Pratt arrived along with his son within the same New Guinean forests and lived there for 2 years. And here's what he aforementioned once he came back to Europe in 1904:
"The forest is filled with immense spider webs, six feet in diameter. it's plain-woven in massive cells - concerningan in. at the sting of the online and one-eighth of it within the center. the online is extremely robust, and, of course, the natives quickly worked out the way to take advantage of it in business, forcing an outsized, hazelnut furry spider to serve man.
A large bar of bamboo they bend a loop and place on the brink of the spider internet. "Very shortly the spider weaves this comfy frame" - and a good internet is ready!
In the river works, wherever the subsided current circles little whirlpools, catch fish with this net: choose it up from below and throw it onto land. "Neither water nor fish will tear a mesh.
Alas, and Pratto, few individuals believed that New Guinea's spider internet caught fish. however, shortly, alternative researchers saw it with their own eyes in Papua, Fiji, king Islands and alternative islands. New books and articles concerning this have already written heaps. it's aforementioned that even butterflies, beetles, little birds and round the bend ar caught by enterprising youngsters of the forest with spider webs. And it appears as if the fish ar force out of the water consideration a pound and 2 each!
They have additionally unreal otherwise of fishing with spider webs. They bend the ring with a hoop, braid it with a spider internet of nephiles, lure ants and their eggs from higher than and let this stacked internet of tropical sample swim with the present. little fishermen bait from below, out of the water, and acquire tangled by gills within the internet. Down watercourse hoops with a catch from the water ar chosen. 2 or 3 such floating nets will catch a dozen fish associate exceedingly|in a very} quarter of an hour.
Recently, the strength of the nephilic internet has additionally been tested by experimentation. The thread thickness of 1 tenth of a millimeter withstands eighty grams (silkworm thread - solely 4-15 grams). it's thus elastic that it stretches virtually 1 / 4 of its length and doesn't rush. A meter-long silkworm thread stretches while not breaking solely 8-18 millimetres.
The fabric from internet of a nephila of gold color amazingly air and easy; at an equivalent sturdiness its abundant diluent than silkworm-silkworms, and at an equivalent thickness - far more powerfully. Yarn internet is collected from the shadows of nephiles or unwind their egg cocoons. however it's higher to drag it directly from the spider, that is placed during a box - it sticks out solely the tip of his abdomen with spider webs. The warts force out of the warts by the elastic threads "just because the cocoons ar straight," says a good skilled in silk production, J. G., World Health Organization is additionally associate skilled within the field of silkworms. Rostan. - during this means, you'll be able to move four thousand meters of silk thread from one spider during a month. A thread straight from a silkworm cocoon, reckoning on its breed, is 300 to 3 thousand metres long.
Different ways from totally different spiders experimenters received, for instance, threads of such length: 1) for 2hours from twenty-two spiders - five kilometers, 2) for a few hours from one spider - 450 and 675 meters, 3) for 9"unwinding" of 1 spider throughout twenty seven days - 3060 meters.
The best results were achieved by superior Kambue, exploring the silkworm capabilities of the Madagascar spider Galaba. In the end, this ingenious man managed to boost his business most that living spiders in little drawers "connected" on to the weaving machine of a special pattern. The machine forces the threads from spiders and forthwith wove the best silk from them
In the wide production of spider webs, even nephiles, it's unlikely to ever come: it's tough to take care of the farms of silkworm spider - what to feed them? so, spider webs ar 12-14 times dearer than silk fabricated from caterpillar cocoons.
