How Spiders Make Their Webs
WouterSpiders make webs to catch prey. They spin a thin sheet of silk, which sticks to the prey and prevents them from escaping. These webs can be a very efficient way of gathering food. However, not all spiders use their webs for hunting. Some may use the web for catching only a few flies or other insects, while others use the web for a wider range of purposes.
Spiders usually have spinnerets on their abdomens, which spin the silk into a thread. The silk is a complex structure, which is composed of filaments from the spinnerets, as well as unconnected areas. In order to make a spider web, the spider begins by laying down a temporary spiral.
The spider then rolls it up, leaving a permanent sticky spiral. The spider also lays down a network of dry silk lines. This creates scaffolding for the spider, as well as providing it with a place to attach its next strand of silk.
The strength of a spider’s web depends on its design and the strength of its spun silk. The spider can build a single line web, which is strung horizontally, or a concave web, which is strung at an angle.
Spiders that create a knockdown web capture prey by trapping the insect. These webs usually occur in undergrowth or gardens. The webs are built on the ground or in leaf litter. The silk threads are strung vertically or horizontally, and they are usually angled to catch a wider variety of prey.
