What Does the Joro Spider Look Like?

The Joro Spider’s size and striking colors make it impossible to overlook. Owing to sexual dimorphism, there’s a significant visual difference between males and females, making each encounter with these spiders a unique experience.

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: Much smaller than females.
  • Color: Darker, less vibrant, with more subdued colors.
  • Web: Does not build webs as females do.

Also, the webs of Joro Spiders are quite distinct in themselves. They are large, golden, and incredibly strong, capable of trapping a variety of insects.

Where is the Joro Spider Found?

Noted for their adaptability, Joro Spiders have been found in diverse habitats, challenging the assumption that they require expansive natural spaces to thrive. Their presence near urban areas and highways is peculiar for a species that hunts using web vibrations, indicating their ability to adapt and flourish in varied environments.

Is the Joro Spider Dangerous?

Despite their size and foreboding appearance, Joro spiders are not deemed a significant threat to humans. Their fangs, although capable of biting, are small, and they tend to avoid confrontations. Thus, the anxiety they may provoke is more about their massive appearance rather than any real danger they pose.

Where Did the Joro Spider Come From?

The Joro Spider, originally from East Asia, is thought to have been accidentally introduced to the U.S. through shipping containers. This accidental migration explains their initial sightings near ports and their gradual spread across the eastern seaboard.
