蜘蛛如何编织蜘蛛网

• 第一步

检查用于造丝编网的器官。蜘蛛的腹部是一个用蛋白质来制造液体丝绸的器官。每个蜘蛛有1到4对穿孔管腺体，这被称为吐丝器。蜘蛛将液体丝绸

• 第二步

 观察蜘蛛是如何开始织网。它发出一缕粘丝并期望随风而动。当它掠过一些物理或棍子时，蜘蛛开始沿着之前的丝往返编织，直到丝足够结实以支撑整个网。

• 第三步

Notice the meticulous system a spider uses to spin its web. After securing the primary thread, it weaves radials around the central point. The spider may use non-sticky thread for this or oils its legs with a substance from its mouth so it doesn't stick to its own web. The spider continues to spin several circular trails around the radials and then finishes the web from the outside working in.

 

Study the silks used by the spider for its various purposes. The web itself isn't usually a sticky silk, but the thread it uses to catch and wrap its prey is very sticky. It uses a different type of silk to make a cocoon for its eggs. If a widely held belief is true, a rope of spider silk 1-inch thick could support a weight of 84,000 tons.

Step 5

Learn to recognize the different types of spider webs. One kind is the orb web, which is oval in shape. Funnel webs are usually on the ground, spun on long grasses or other supports. There are tangle webs (what we call cobwebs), tubular webs and sheet webs. A different type of spider makes each kind, and the structure varies with the purpose of the web.
