What is the Joro spider?

Native to Japan and other parts of Asia, the Joro spider, or Trichonephila clavata, is a black and yellow giant, venomous, flying spider that can grow up to four inches.

They were first discovered in 2013, but were found in Georgia in 2021.

Joro spiders utilize a technique known as ballooning, where they release silk threads into the air, allowing them to be carried by the wind, according to NJ Pest Control. This is where "flying" comes from.

How to identify a Joro spider web

Joro webs are three to nine feet in diameter. It is made up of five types of silk and is very strong, stretchy and coated with a watery, glue-like substance that allows them to easily catch their prey. They can be found near the edge of forests, parks and streams of water. Webs are generally six to 10 feet above the ground. Many have been found near the exteriors of homes, according to a USAToday report.

Is the Joro spider venomous?

The spider is venomous, but not deadly to humans, it can cause discomfort and allergic reactions in some individuals.

In their native habitats, Joro spiders are just like the common spider — controlling insect populations and acting as natural pest controllers. They prey on anything such as flies, ants, stink bugs and mosquitoes.
