These markings help female camouflage against foliage litter and barque, volunteer protection as they defend their eggs.
Visual Acuity and Eye Patterns
Leap spider have four distich of optic, and the system is alike in both sex. Yet, the orientation and mapping of their prior average eye can sometimes hint at their adulthood and sex.

They are ambush predators; they will wait for vibrations to find target and then pounce. Males, conversely, are explorer. They wander extensively during the union season, often jumping long distances to find a female in a new location. This roaming behavior pose them at higher peril of being eat, which is why their courtship rite are so critical for their selection.
