Thus, the portia approaches its almost unperceived prey while passing. Some techniques of hunting: When the portia attacks a spider being in its fabric, that Ci, not to be made locate, advances with the liking of the vibrations of the fabric, while evolving/moving more quickly for example, when there is wind and while remaining motionless when no vibration occurs on the fabric. Another technique of hunting, when its victim is blind, the portia can make vibrate the fabric of its victim, simulating a Insecte captured and leading its victim to advance until it in order to capture it.
It can even attack a spider while being suspended with its own wire, in order to avoid being made locate. This commnunic spider in the form of gestures with its congeneric.
