Answer:
Spider webs are built from silk, which is produced within the body of the spider and pulled out of two openings—spinnerets—with the spider's hind legs.
All spiders have two claws on their feet, but web-spinning spiders have three. They are used not only to pull the silk but also to grip and release the web’s threads and provide traction as they move along the web.
Spiders spin two kinds of silk:
Sticky silk or viscid silk. Used to capture prey, this stretchy, wet silk makes up the spiraling threads of the web.
Non-sticky silk or dragline silk. Used to strengthen and provide structural support of the web onto which the viscid silk is woven, this silk is stiff and dry.
Types of Spider Webs
There are three main types of webs: orb webs, funnel or sheet webs, and the irregular webs of house spiders.
Orb Webs: Orb-weaver spiders build their webs almost completely through touch, because, although they have eight eyes, they actually have poor eyesight. According to a Newton Nature Bulletin from the Argonne National Laboratory, "Beneath her abdomen are six spinnerets that can be extended or compressed and used like the fingers of a human hand. Each spinneret has 'faucets' and 'spools' connected by tiny tubes to several types of glands." The silk begins as a liquid then solidifies and becomes stronger exposed to the air. To build the web, the orb-weaver sets the foundation with radial and framework threads using dragline silk. The viscid silk is then applied on top of this foundation, made sticky by "dots" of a glue-like substance. The web generally takes about an hour to build.
Funnel Webs: These sheet-like webs are generally spun outside by funnel-web or grass spiders. As explained in the Newton Nature Bulletin, "Each sheet extends outward from a funnel-like opening beneath which the spider lurks in waiting for grasshoppers and other insects that may alight upon It. She constantly enlarges the web and, if undisturbed, it may become a square yard in the area." Generally set horizontally, the web "funnels" down into a shelter, such as a crack in the ground or a rock crevice or thick vegetation. The funnel opening can be over a foot long, with the sheet extending up to three feet.
Irregular Webs: House spiders usually build their webs at night, and is much more haphazard than that of the orb weaver. This web "has a central sheet of densely woven silk which serves as a hiding place and is anchored by numerous guy lines that are long and strong," the Nature Bulletin states. This spider uses its back comb-like legs, with their row of curved bristles, to capture prey by tossing the silken strands of the web over an insect that flies or wanders into it.
