It only takes between 20 and 30 minutes for the arachnid to build its web. First, the radii must be placed at set intervals. The spider, then, crosses the radii in pendulums and round turns to set the insect-catching zones. After the work is completed, the spider settles at the hub of the web and stretches out its legs. It can now feel each vibration that occurs on the web, thus catching prey trapped its natural structure.
