Jumping spiders are not the only spiders family that mimic ants also Clubionidae (sac spiders) in the genera Castianeira and Apochinomma imitate ants. Five genera of ant-mimicking spider occur in Australia: Judalana, Ligonipes, Rhombonotus, Damoetas and Myrmarachne. The jumping spider can be found everywhere if the sun is shining, on trees, grass and rocks. At night or during rainfall the spiders hide in a dry spot under a small web. Their large eyes give them excellent eyesight. As most spiders they also have four pairs of eyes.
