Information

Although Jumping spiders look peaceful, they are active hunters that stalk and pursue prey until close enough to attack. They select prey on the basis of experience and seemingly they have a preference for slow moving prey. Jumping spiders are poly-phagous meaning that they consume almost anything. Due to their complex eight eyes arranged in three rows, they possess an excellent vision, and where many spiders are nocturnal, Jumping spiders are diurnal.

Large Jumping Spiders such as Phidippus spp, which are found in North America, reach lengths of 8-15 mm. Jumpings spiders sometimes hunt in pairs, male and a female together, and during daytime. That relationship is sympatric meaning that it is mutually beneficial.

Their vision is important for catching the prey they pursue. According to several sources (Land 1969ab & Blest et al. 1990)the spatial accuracy of Jumping spider's eyes is approaching that of large mammals. More detail, please go to this link http://www.jumpingspider.net/
