Spider webs, may be the structure of the artificial nature of the most beautiful animals and complicated. But some types of spiders make it even better. They built it a step further.
The structure of spider webs extra features or stabilimenta stabilimentum scientific name. The name is actually taken by accident, even arise because of an error which is when researchers suspect that this pattern is intended to make the spider web is stable. This theory was later disproved. 
Looks like the function of these extra patterns can vary. Spiders build this pattern repeated itself may be up to ten times. Some of them make this pattern does not come from his own net but from the remnants of anything, including the former their own eggs or anything that is near the net. 
The pattern of extra nets can be found among some species of spiders - but the best examples is that of Argiope species. These extra patterns, often almost mathematically precise 45-degree angle, seem to be made to "memelarkan" their bodies so that makes it less attractive predators. Sometimes this leads to a vertical pattern and spiders are younger may make it shaped like a disc. 
Answering the question why an extra pattern is made seems to be not simple. Some consider it to give extra protection because it makes the spider appear larger or as camouflage. Or conversely it makes it more visible than his own net making it more easily seen by such birds. More like a "stop sign" to other animals. 
Thermoregulation, this theory says that this extra pattern helps the spider maintain optimal body temperature to survive in any weather. 
There is also mention that spiders have aesthetic - like human beings also have aesthetic - as well as other animals shown to improve the environment for the pursuit of something. 
It might, encouragement of reproduction is the reason why this extra pattern is created. When a female is ready to reproduce what better way to attract the male in addition to beautifying the net? 
Most of this extra pattern is created from the net itself other than some kind of combine it with any object nearby. In Nephila species, the remains of prey, too attached to this pattern is more interesting with the intention of another prey. 
Some types of spider webs decorate even more organized with more complex patterns, as if nature shows that they're the best designer on earth. If you look at the pictures below it does not look perfect but enough to make us wonder why they make this extra configuration.

Later mentioned that stabilimenta used to better attract prey spider. Often see insects in the evening gathered near the lights? Extra pattern spider web is believed capable of reflecting ultraviolet rays so meanrik more prey to approach the net.

Whatever the reason, it shows out there there are many natural wonders that we do not realize happen every day. Even by small animals that we almost never notice.
