What Does the Joro Spider Look Like?
The Joro Spider stands out for several reasons. It’s a large, vibrantly colored spider with a massive web. Seeing a large Joro usually means it is a female, as the spiders exhibit sexual dimorphism. This means that the females and meals vary in appearance from one another.
Here’s how to tell male and female Joro spiders apart:
Male:
- Size: Much smaller than females.
- Color: Darker, less vibrant, with more subdued colors.
- Web: Does not build webs as females do.
Female:
- 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.
The Joro Spider web is also distinct, as they are large, strong, and golden. The webs can trap a variety of insects.

Their ability to thrive in different environments, including urban areas, underscores their versatility and potential for wider spread.
Is the Joro Spider Dangerous?

Where Did the Joro Spider Come From?
