跳蛛依靠视觉刺激来捕捉猎物。每一个狩猎行为都是由负责这种行为的3双眼睛中的一双或多双眼睛介导的。这四对小小的眼睛的功能还没有得到证实。使用两种不同的检测后搜索策略。一个使蜘蛛能够在奔跑中捕捉猎物，另一个控制捕获静止的猎物。每种策略的唯一组成部分是追逐，前外侧眼睛的功能，和跟踪，前正中眼睛的功能。协作视觉机制导致从一种行为模式到另一种行为模式的平滑过渡。这两种策略都采用了共同的行为元素，利用4个前眼的专门属性。成功捕获猎物是衡量它们生理和行为同步性的一个标准。向角速度大于15 °的目标短距离跳跃。当前中眼被覆盖时，前外侧眼介导了这些变化。这些短跳跃距离和目标速度之间存在显著的负相关（P < 0.005），前外侧眼必须处理与变量相关的信息。单侧封闭相邻的一对前眼（前外侧和前正中）表明，由正常眼睛传递的视觉信息控制着身体特定一侧的特定狩猎姿势。同样，失明的男性表现出双边腿抬起对方和女性的反应。视觉控制的机制，在竞争和求偶行为可能不同于那些直接捕食序列。
Jumping spiders rely on visual stimuli when catching their prey. Each hunting action employed is mediated by one or more of the 3 pairs of eyes responsible for this behavior. No function has yet been demonstrated for the tiny 4 pair of eyes. Two distinct post-detection hunting strategies are used. One enables spiders to catch their prey on the run, and the other controls the capture of stationary prey. Exclusive components of each strategy are chasing, a function of the anterior-lateral eyes, and stalking, a function of the anterior-median eyes. Collaborative visual mechanisms result in a smooth transition from one mode of behavior to another. Both strategies employ common behavioral elements that exploit specialized properties of the 4 anterior eyes. Successful prey capture is a measure of their physiological and behavioral synchronization. Short jumps towards targets moving at an angular velocity of more than 15.degree./s are mediated by the anterior-lateral eyes when the anterior-median eyes are covered. A significant negative correlation (P < 0.005) is shown between these short jump distances and target velocity; the anterior-lateral eyes must process information relative to the variables. Unilateral occlusion of an adjacent pair of anterior eyes (an anterior-lateral and an anterior-median) demonstrates that visual information transmitted by the sighted pair controls the specialized hunting postures on that particular side of the body. Similarly blinded males exhibit bilateral leg-raising responses to each other and to females. The mechanisms of visual control in agonistic and courtship behavior probably differ from those that direct prey-catching sequences.
