Spiders are noted for web building, yet many kinds never use their talents in this way.
Instead of building silken traps they hunt their prey, stalking and leaping on their victims or
hiding or pouncing on them. Webs vary in style from the irregular cobweb that neat
housewives constantly dust away, to the beautiful silken orbs that we so often find in a
garden. There are four general types besides the irregular mesh and the orb; we find the
funnel webs and the sheet webs.
Until they reach full growth male as well as female spiders spin silk and construct webs.
However, after their last moult, the males no longer engage in spinning but often linger on
or near the webs of their mates. Messy as an irregular mesh web may appear, it is
nevertheless built on a definite plan and is very efficient. The central maze is a widespread
trap. Within this maybe a densely woven sheet, combining such materials such as leaves and
grains of sand with the silk thus serving as a shelter for the little builder.
Anchoring the maze firmly to supports are long lines, which have small knobs of sticky silk
near their base. When a small insect brushes against a sticky line it is snared and as it
struggles, the line breaks and tethers the victim. The common house spider and other
members of the family prepare webs of this type. The sheet web has been developed on a
platform like plan, with the webbing closely woven on a horizontal plane. A ‘platform’
results and on this insects jump, fly or drop, often being stopped in their flight by lines which
the spider has crisscrossed above the platform.After building the platform or sheet, the spider clings to its underside. At times it constructs
another sheet below so that it is sandwiched between two silken barriers. When victims land
on the top sheet, it pulls them through the silk. Sheet webs are built to last a long time. Even
more permanent than these sheet webs is the handiwork of the funnel web spiders.
Outside the retreat in which it lives, a member of this family starts to spin its webbing until
a smooth runway is created. If this is on the ground it suggests a sheet and if suspended from
vegetation, a tiny hammock. In any case it looks like a good landing field to insects. However
after alighting, they find themselves bogged down in a soft trap, and the spinner, which has
been waiting at the mouth of its funnel retreat, quickly attacks them. As one of these spiders
grows to adulthood, and as long as it remains active, it continues to add to its structure.
Gradually a thin small mesh becomes a large thick blanket. In autumn these webs are at their
peak, and especially when covered with dew, maybe seen spreading over acres of grasslands
like dainty fairy woven carpeting.

b). SUMMARY:
Spiders are known for web design, yet many species do not use their talents in this way. Instead of making silk traps they hunt their prey, lurking and jumping for their prey or to hide or throw themselves upon them. Webs vary in style from unusual to clean housewives always dust off, in the beautiful silk orbs we often find in garden. There are four common types besides the non-standard mesh and the orb; we find i web pages and web sheets. Up to full maturity the male and female spiders spin silk and form webs.
After their last spin, however, the men are no longer involved in spinning but are often delayed or near the web of their spouses. It's as bad as an unusual mesh web may appear, of course however it is built on a solid plan and works very well. The maze in the middle is wide trap. Inside this is probably a thick woven sheet, which connects such things as the leaves once sand grains and silk thus serve as a shelter for the young builder.
Long lines with adhesive silk knots fasten the maze firmly to the bases. When a small insect scratches on a sticky line it is caught again as it is struggling, the line breaks and binds the victim. Common house spiders and others family members fixing websites of this kind. Web sheet made in a platform like a plan, with a thread woven near the horizontal plane. 'Court' results and in this case the insects jump, fly or land, usually stopped in their flight by rows . The spider cuts across the platform.After building a platform or sheet, the spider attaches itself to it. Sometimes it builds another sheet below to be inserted between the two silk barriers. When the victims came down on the top sheet, pull them with silk. Web sheets are designed to last longer. I mean more durable than these web pages is the work of a funnel web spider.
Outside the shelter where you live, a member of this family begins to roam around a smooth airline was built. When this is low it raises the sheet and when suspended grass, a small hammock. In any case it looks like a good platform for getting rid of insects. However after landing, they find themselves trapped in a soft trap, with a spinner, which we have he watches over the mouth of his wickedness, and he strikes them down quickly. Like one of these spiders it grows old, and as long as it is active, it continues to add to its structure.
Gradually the tiny net becomes a large, thick cloth. In the fall these webs are in their place the peak, and especially when it is covered with dew, may appear to be spreading across the hectare grassland like a woven rug of fairy tales.
