Giant Venomous Flying Spider With Four-Inch Legs May Finally Be Arriving in Louisiana

The Joro spider, an invasive species from East Asia, is potentially making its way to the Bayou State. This brightly colored arachnid, known for its vivid yellow and grey body and ability to "fly," has been moving across the eastern United States, with sightings reported as far west as Mississippi and soon as far north as New York.

The Joro spider, first introduced to North Georgia around 2010, has steadily expanded its territory. According to a peer-reviewed study by invasive species expert David Coyle, the spider is "here to stay," with its comfort range in its native habitat matching much of North America. This means that Louisiana could soon see these spiders settling in.

These spiders are not just notable for their size—female Joro spiders can have a leg span of up to four inches—but also for their unique method of travel. Utilizing a technique called ballooning, Joro spiders release silk threads into the air, allowing the wind to carry them over long distances. This ability has led to their spread across multiple states, including Florida, Alabama, and the Carolinas.

Despite their venomous nature, experts reassure that the Joro spider poses no real threat to humans. The venom is primarily used to subdue their prey, which includes butterflies, wasps, and cockroaches. There have been no reported cases of the spider causing harm to people or pets. "We have no evidence that they've done any damage to a person or a pet," said David Coyle.

However, the presence of Joro spiders could have ecological implications. They may compete with native spider species for food, and their impact on local ecosystems is still being studied. Andy Davis, a researcher at the University of Georgia, has noted that while the spiders could feed native bird species with their daily catch, their overall effect on the environment remains uncertain.

David Nelsen, a professor of biology at Southern Adventist University, emphasized that while the Joro spider might incite public hysteria due to its appearance and size, it is relatively harmless.

Nelsen pointed out that more significant threats come from other invasive species that can damage crops and trees, exacerbated by global trade and climate change.

While most Louisiana residents may not be prepared for this potential new arrival at first sight, it is essential to stay informed and understand that while the Joro spider might be startling to encounter, it is not a danger to human health.
