Prey capture sequence was shot by high speed camera (300 frames/s). A syrphid fly was put on the web. The spider firstly relaxes its legs and turn to the prey. Its 4th legs are used to hold its body. Then, the spider jerkes web thread by its 1st and 2nd legs. The spider wraps the prey using its 4th legs and uses the 1st and 3rd legs to rotate the prey.
