Adults

  • Size: Typically, the body length of adult spiders ranges from 10 to 15 mm for males and 12 to 18 mm for females.
  • Color: They exhibit a mix of brown, gray, and yellowish tones, often with a distinctive leaf-like pattern on the abdomen, which helps in camouflage.

Eggs

The female lays eggs in a silken sac, which she guards diligently until they hatch. The sac is often hidden in crevices or under rocks to protect it from predators.

Spiderlings

Young spiders, or spiderlings, emerge from the eggs looking like miniature adults. They are independent from birth and start hunting small insects soon after their first molt.

The Web

Unlike many spiders, Zoropsis spinimana does not construct webs to catch prey. Instead, it relies on its agility and hunting skills, wandering at night to hunt down its prey.
