If you’ve noticed a strikingly large spider with a web that seems to command the space between your trees, you’re not alone. Many residents in Georgia have reported sightings of what is believed to be the Joro Spider, a species of orb-weaver spider that has been gradually making its way across the eastern United States. 

This guide is tailored for you, aiming to demystify the presence of this intriguing arachnid in your surroundings and if spider extermination intervention is needed. 

Identifying the Joro Spider: 

The Joro Spider, with its sizeable physique and vibrant colors, easily stands out from the more familiar spiders you might encounter. This difference is particularly pronounced between males and females due to sexual dimorphism, a biological phenomenon where the two sexes of the same species exhibit different characteristics beyond their sexual organs.

Here’s how to tell male and female Joro spiders apart:


  • Size: Large, with a body length of about 0.75-1 inch and a leg span of up to 4 inches.
  • Color: Bright yellow and blue body with distinctive red markings.
  • Web: Builds large, intricate webs that can span up to 10 feet.


  • Size: Noticeably smaller than their female counterparts.
  • Color: Darker, less vibrant, with more subdued colors.
  • Web: Does not build webs as females do.

The Joro Spider’s web is a marvel in itself—large, golden, and incredibly robust, effectively capturing a wide array of insects.

Where is the Joro Spider Found?

Initially believed to need a large natural habitat in tropical climate for optimal survival, the Joro Spider has defied expectations by showcasing an impressive capacity to acclimate to diverse environments, even thriving in urban landscapes. Observations of their proliferation near highways and within cities have underscored their remarkable adaptability, prompting inquiries into the extent of their potential range expansion. 

Is the Joro Spider Dangerous?

Despite their imposing appearance, Joro spiders typically pose minimal threat to humans. While possessing fangs with the capability to bite, these arachnids generally exhibit timid behavior, preferring to retreat rather than engage in confrontation. 

The History and Future of Joro Spiders: 

Originating from East Asia, the Joro Spider is thought to have been inadvertently brought to the U.S. via shipping containers, leading to their presence in various states, including Georgia.

As for the Future of the Joro Spider in Georgia, it appears that the Joro Spider is here to stay. With their adaptability and successful breeding patterns, their numbers are likely to grow, further embedding themselves into the local ecosystem.
