Parachuting Joro Spiders Set to Invade New York This Summer
The invasive joro spider, known for its unique parachuting abilities, is expected to make its way to the New York area this summer, according to experts familiar with critter migration. Originating from East Asia, these spiders travel by floating on the wind with their silken threads, giving the appearance of flying.
Despite their intimidating 4-inch leg span and 2-foot-wide webs, scientists reassure that the joro spider is not aggressive. In fact, a recent study conducted by the University of Georgia found that these spiders are rather timid. While most spiders quickly retreat when they sense danger, the Trichonephila clavate species has been observed freezing in place for extended periods.
These orb-weaving spiders have been known to construct their webs in unconventional locations such as traffic lights and mailboxes. Research from the University of Georgia indicates that joro spiders can tolerate vibrations and noise, making them well-suited for urban environments. Since 2021, their webs have been spotted between power lines, along porches, and across hiking trails in the southern United States.
Having already established a significant population in the South, with sightings reported as far north as Maryland, the joro spider’s expansion to the Northeast is deemed inevitable by experts. While their presence may be unsettling to some, it is important to note that these spiders pose no threat to humans and actually help control the population of invasive pests like the spotted lantern fly.
Entomologist Louis Sorkin, formerly of the American Museum of Natural History, emphasizes that the joro spider is not venomous and does not pose a danger to humans. David Coyle, an assistant professor at Clemson University, further confirms that these spiders are likely here to stay based on his research published last October.
As the summer approaches, residents in the New York area are advised to familiarize themselves with the joro spider and its habits to coexist peacefully with these fascinating arachnids.
