Physical Description and Identification

Adults

Color: They are generally black and brown with some light markings. Male spiders are incredibly colorful, showcasing iridescent hairs all over the body.

Other Characteristic Features: Their front legs are longer than the rear legs, but they use the rear ones to jump. The front legs are used for grasping their preys. The spiders also have a different type of cephalothorax than their cousins.

Eggs

Jumping spiders lay 100-150 eggs in a lens-shaped egg sac. The sac is hanged from the wall of the silken retreats.

Spiderlings

Young spiderlings go through molting phases a couple of times.

The Web

Most jumping spiders do not make webs, but a few species do, but even they don’t rely on webs for hunting.
