Researchers have spotted another invasive species in Bucks County, according to a staff report from 6abc.

The spotting of Joro spiders, or Trichonephila clavata, was confirmed by the University of Georgia’s Center for Invasive Species on September 5.

The black and yellow arachnid is about the size of a palm and can grow up to four inches. The Asia-native spider is venomous but non-aggressive, and its fangs cannot break human skin.

According to author Andy Davis, a research scientist at the University of Georgia’s Odum School of Ecology, while researchers advise killing certain invasive species, such as the spotted lanternfly, the Joro spider can be left alone.

The arachnid can float through the air on balloons of spider silk when it is young.

“Joro spiders utilize a technique known as ballooning, where they release silk threads into the air, allowing them to be carried by the wind,” explained the NJ Pest Control.

Scientists do not believe there will be a large invasion of Joro spiders. The species were first spotted in the United States around 2013.
