A new type of spider, the invasive East Asian Joro spider, may be making its way to Middle Tennessee, experts have warned. Known for its large size and bright colors, this spider was first seen in Maryland in 2010 before migrating to Georgia and South Carolina in 2021. Scientists suspect it may have reached the United States by hitching a ride on shipping containers from East Asian countries like Korea, Japan, or China.
As the Joro spider prepares to move north with the wind, experts anticipate a rapid increase in its population, estimating it could reach Middle Tennessee this year. While the spider does have venom, it is not considered deadly or medically relevant to humans or pets. Despite this, scientists are still studying how the new spider will affect the local ecosystem.
With concerns about the impact on native species, experts are urging people to refrain from killing spiders unless they are sure they can identify the Joro spider. The self-reported sightings of the spider in locations such as Columbia and Smith County indicate its potential spread. While some questions remain unanswered, scientists are working to understand the implications of the invasive species.
As Dr. Amarasekare mentioned, spiders have been around much longer than humans, and it is important to be respectful of their presence. With further research needed to fully comprehend the impact of the Joro spider, experts advise caution and observation before taking any actions.
