Joro spiders – described in social media posts variously as “venomous,” “giant,” or “flying” – have been the topic of a lot of discussion online this week.
The spiders are an invasive species that scientists say are spreading throughout the United States.
They’re “spreading like wildfire,” according to a Clemson University press release.
David Coyle, an assistant professor at Clemson, spotted a Joro spider in his yard in 2021 and started tracking the species.
Coyle and his collaborators published a 2023 study that showed that not only are the Joro spiders spreading along the east coast, but that they may eventually spread throughout the country.
“These things are here to stay,” Coyle said.
The study, he said, “shows that their comfort area in their native range matches up very well with much of North America.”
So, why is everyone online freaking out about this now? Well, look at them.
Also, they can fly.
CBS News on Wednesday published a report about Joro spider spread on the east coast, bringing fresh attention to the spider invasion.
Joro spiders, though, aren’t as fearsome as they look, the Associated Press reports.
Yes, they can fly – but only when they’re young – using a technique called “ballooning” that’s honestly more like gentle float.
They are technically venomous, but David Nelsen, a professor of biology at Southern Adventist University who contributed to the original study, told the AP that the worst a human might experience from a Joro spider bite is some itching.
And, yes, they are invading, but they aren’t the only ones. Invasive species have become an increasingly common problem thanks to factors like global travel, shipping and climate change.
Oregon is home to several common species of spider, most of which are also harmless – and even beneficial.
