According to researchers from the University of Georgia, large spiders that are native to East Asia could spread to the East Coast of the United States. A recent release mentions this.  

The Joro, also known as Trichonephila clavataThe spider, pictured here, is part of a group known as “orb weavers.”Their organized, three-dimensional, wheel-shaped webs give rise to their name.

According to the study, Joro spiders are approximately three inches in length, with their legs fully extended, and have red, yellow, and blue markings on their bodies. They have 77% more heart rate and have a metabolic rate that is double theirs. They can even survive a sudden freeze that could kill their family members.

Rick Hoebeke first identified them in 2014 at the Georgia Museum of Natural History. In 2021, millions of these spiders and their golden Webs were found throughout Georgia. A few have been seen in South Carolina. 

The Joro spider is a common species in Japan. It is also found in areas with similar climates to the U.S. 

“Just by looking at that, it looks like the Joros could probably survive throughout most of the Eastern seaboard here, which is pretty sobering,” said Andy Davis, the study’s co-author, in a statement. 

It is not known when and how the spider arrived in the United States. They were also present in Georgia in 2021. According to WGCL-TVThe theory is that the spiders were brought in a container from overseas and dropped on Interstate 85. 

Per the statement released by the University of Georgia, experts are split when it comes to how the large spiders’ presence could impact their current environment. Spiders are well-known for their ability to catch pests and some believe they are both harmless and helpful.

Others believe it is prudent to be cautious as the spider population has increased in an area that they are not native.
