What Does the Joro Spider Look Like?

The Joro Spider catches the eye with its impressive size, sprawling web structure, and striking coloration. If you happen upon a sizable one, it’s probably a female, given the species’ sexual dimorphism, where males and females exhibit distinct physical characteristics. Curious about telling male and female Joro spiders apart? Here’s how you can distinguish between them:


  • Size: A large body, roughly ¾ inch to 1 inch in length, with legs spanning up to 4 inches.
  • Color: Vibrant yellow and blue shades, highlighted by noticeable red markings.
  • Web: Weaves large, intricate webs that can extend up to 10 feet.


  • Size: Noticeably smaller than the females.
  • Color: Darker tones and less vibrancy, with more subdued colors.
  • Web: Unlike the females, the males do not spin webs.

The webs created by Joro Spiders are distinctive. They are sizable, golden-colored, and incredibly strong, able to ensnare a diverse array of insects.

Seeking assistance from a professional spider removal expert can help offer peace of mind.
