Passing away zone
I hide, and an obi (I hide and am charged), a white belt (sea bream to vomit), the studio booby mentum (British: stabilimentum) are decoration of the threads added to a Japanese yen network of the spider. We have many opinions for the function. I hide, and the name of the obi was used by a judgment that I am effective in hiding the figure of the spider than old times in Japan, but a white belt is used for a technical term to avoid a judgment of such, foreseeing.

Origin
I am said to be it when I did nine kinds of different evolution even if there are few studio booby menta.
Money-spinner and トゲグモ make a studio booby mentum with a thread. ゴミグモ and Allocyclosa bifurca which are their friend are garbage and egg のうをつるす to the studio booby mentum which they made with a thread more. Those studio booby menta evolved independently from コガネグモ, but the decoration of the studio booby mentum of Allocyclosa bifurca is similar to コガネグモ [1].
Shape
They hide, and obis are seen in several types of spiders of コガネグモ department, アシナガグモ department, the ウズグモ department well. The コガネグモ genus which オーストラリアコガネグモ in particular belongs to is famous. The spider of the コガネグモ genus forms a passing away zone of the zigzag design [2]. Other spiders create decoration to cover all hubs of the net, too.
Function
I hide, and we have many opinions for the function of the obi, and, as for various spiders, it is thought even if I use it for the purpose of each and others. It is told another view to be to protect a spider by making a figure look have a bigger camouflage するためや. By other opinions, it is told the animals such as the birds which are not given damage in spider silk to be to let a spider be outstanding [3]. I was avoided with a thing advocated at first now, but it was thought that the decoration stabilized a net. When I let I am covered with the recent opinion, and an ultra violet light reflect in the obi and attract game, I am said to be it [4]. The ultra violet light is known to be attractive for the kind of many insects [4]. In addition, temperature control, stress, the adjustment of the thread which I exceeded, an opinion such as the simple seemliness were proposed. When a human being approached, a phenomenon to let I transformed a studio booby mentum, and a net vibrate was seen.
As for the purpose of the studio booby mentum, the opinion to be to make a male come near in a net in the breeding season of the female was proposed. In the investigation carried out in Spanish empty Honda in the summer of 1992, it was confirmed that a male was between a net and studio booby menta of ヤツデコガネグモ [5].
When it is disturbed that I make a studio booby mentum, much ウスグモ except Uloborus gibbosus falls into the ground after taking a rest in the edge of net. It is said that this supports a camouflage theory. The studio booby mentum of ウスグモ is told to be attractive for a Drosophila [1].
Materials
They make all the コガネグモ genus in spider silk, but other some spiders such as ゴミグモ use egg のうや garbage in addition to a thread. It is said that these decoration is to camouflage a spider. And I protect the body from a predator [6]. As other phenomena, the silk spider puts a golden kind on a net. It was revealed that these spiders attracted more game by the recent investigation [7].
Pop culture
After E, the B white observed the studio booby mentum of the net of the spider, insist that hit on the idea of the book "present of Charlotte" [8]; [9].
