Spider webs, may be a natural structure of the animal made the most beautiful and intricate. But some types of spiders make it even better. They built it one step further.
Several types of decorating spider web is even more organized in a more complex pattern, as if to show that they are the best natural designer on earth. If you look at the pictures below do not look perfect but enough to make us wonder why they made this extra configuration.
Structure of spider webs extra features or stabilimentum scientific name stabilimenta. This name was taken by accident, and even appeared because of an error that is when researchers speculate that this pattern intended to make a cobweb stable. This theory was later disproved.
It seems the function of this extra pattern can vary. The spider was building his own pattern many times perhaps to ten times. Some of them make this pattern does not come from his own net but from what remains of it, including from the former their own eggs or anything that is near the net.
This pattern of extra nets can be found among some species of spiders - but the best example is that of Argiope species. This extra patterns, often almost mathematical precision with 45-degree angle, it seems made for "memelarkan" so their bodies do not make it more attractive predator. Sometimes this leads to a vertical pattern and spider younger may make it shaped like a disc.
