Giant, ‘flying’ Joro spiders spreading on the East Coast this summer

This summer, the East Coast may see the arrival of the giant Joro spider, Trichonephila clavata, originating from East Asia. Known for their striking yellow and blue-black colors, these spiders have stirred concerns about an invasion in New York City and New Jersey. Female Joro spiders can grow up to four inches and spin large, strong yellow webs. Although they appear menacing, experts say they pose no threat to humans or pets. Joro spiders are not truly flying but use a method called “ballooning,” where they create silk webs to travel with the wind. Initially spotted in Georgia, they have since spread to several states, likely hitching rides on cars or cargo. While they could impact local ecosystems by competing with native spiders, they also offer benefits, such as pest control. Scientists remain uncertain about the extent of their potential impact in the Northeast.
