# Joro Spider

*Trichonephila clavata*

Joro spiders utilize a technique called 'ballooning,' where they release silk threads to catch wind currents, allowing them to travel vast distances through the air.

## About

Trichonephila clavata , also known as the Jorō spider (ジョロウグモ（女郎蜘蛛、上臈蜘蛛）, Jorō-gumo ), is a member of the golden orb-web spider genus. The spider can be found throughout Japan except Hokkaidō, in Korea, Taiwan, China, and more recently, northeast Georgia in North America. Due to the large size as well as the bright, unique colors of the female Trichonephila , the spider is well-favored in Japan.
