The invasive Joro spider, native to East Asia, has been spotted in Bucks County, Pennsylvania, marking its first appearance in the state. Confirmed sightings involve six individuals, prompting a local entomologist's visit for verification, as reported by Joro Watch. These spiders, known scientifically as Trichonephila clavata, can grow up to four inches long and are recognized for their large, golden webs that can reach ten feet in width. Although venomous, Joro spiders are non-aggressive and pose little threat to humans. First reported in the U.S. in Georgia in 2014, experts believe these spiders could spread rapidly due to their ability to travel by ballooning, wherein they use silk threads to catch the wind. Their potential range may extend throughout eastern North America, possibly moving further north than initially anticipated due to changing environmental conditions.
