Different+Types+of+Spider+Webs


 * Different Types of Spider Webs **
 * __Primitive Webs: __** This kind of web is similar to a spider alert system. The web lines are used to sense vibrations of insects moving nearby. Once the spider senses these vibrations, it emerges from its nearby hiding place and attacks the insect that caused the silk line to vibrate.


 * __Sheet Webs __**: These webs are designed to catch the spider's prey by knocking the passing insects into the sheet of silk, where the spider will bite through the web and eat the insect. Sometimes these can be shaped into a **__funnel web,__** which leads to the spider’s hiding place where it will emerge to catch the prey.




 * __Tangle Webs __**: These webs may also be referred to as cobwebs. These webs consist of supporting threads, a network of tangling threads, and trap threads. The supporting threads keep the structure of the web together, and may knock insects into the tangling threads. The tangling threads are where the insect gets caught or knocked down into the lower trap threads. Here, the spider typically awaits for the arrival of prey. The trap threads are meant for insects who may be crawling on the ground or for prey who has fallen from the upper web portions. These trap threads have sticky droplets on them that the insect gets stuck in. When these threads are broken, the thread is pulled upward towards the spider who then eats its captured prey.


 * __Orb Webs: __** These are the webs that are shaped like a wheel. Orb webs are made out of sticky silk that an insect becomes trapped in upon contact with the web. The spider will then eat the prey that is trapped in the web. Different species of spiders will eat the prey differently (some will wrap it up first, and others will not).




 * __Decorative Webs __**: These webs have patterns woven into them, such as zig-zags, spirals, etc. There is some debate over whether or not the reflection of UV light may cause the web to imitate the appearance of a flower to some insects, thereby attracting more prey for the spider.


 * __Reduced Webs: __** These webs are typically made up of a single strand, or at most, a web in the shape of an ‘H’. While these webs may not catch as many bugs as larger webs, they catch more bugs per strand than other webs. It is likely that more bugs per strand are caught because a single strand is much more difficult for an insect to see than a network or strands made up in a typical web.


 * __Web Casters: __** These spiders create webs that appear similar to a fishing net made by humans. The spider will throw the web onto its prey, and reel the web back in with the captured prey.
