The Portia Spider: A master of Deception
In contrast to most other spiders, Portia Fimbriata both builds a web and hunts away from its own web. Another feature of Portia is that it prefers members of it own web. Another feature of Portia is that it prefers members of it own species over insects as food. For this reason Portia's field of activity is generally other spiders' webs. It uses a fascinating stratagem when hunting.
Generally, Portia will land on web while the wind is blowing or while an insect is struggling to free itself. Such strong vibrations mask the shaking caused by a Portia on the prowl. To look at, it resembles a scrap shaking caused by a Portia on prowl. To look at, it resembles a scrap of vegetation blown into a web into a web by the wind. Unlike other spiders, which jump excitedly on their prey when they see it, Portia moves slowly. Once it is installed on the web, it manipulates, plucks and slaps the web silk with its legs, mimicking a trapped insect. When the owner of the web approaches, Portia is ready and waiting in ambush.
Portia spiders deceive members of their own species by imitating them. for example, Portia mimics the mating ritual of the Euryattus spider, which lives in a rolled-up leaf suspended by silk cables. Sitting atop a female spider's home, Portia rocks the leak, dancing atop it like a Euryattus male. Fooled for the moment, the spider emerges from its home
How does Portia match signals with different method of hunting? It is not logical to suggest that a spider could have an "imitative skill" and because of this should choose such an interesting hunting technique. The spider hunts in this way because that is how it was created by God. In such example, God Shows us the incomparable nature of His art of creation
