ANDERSON COUNTY, S.C. —
If you have been on edge dodging spider webs around your home, you are not the only one. The Upstate is reporting increased sightings of the Joro spider, an invasive species native to East Asia.
Female Joro spiders can be identified by unique yellow markings, including yellow and black striped legs, large, speckled bodies, and pink markings on the underbelly. The males are small brown spiders, and typically several of them will surround the female in the web.
Joro spider webs can be distinguished by their strong strands and golden color, something native species lack in their webs.
A common misconception is that Joro spiders can fly. This is called ballooning, which Coyle said is when eggs hatch, and a group of the babies crawl up something tall, release a strand of silk, and the wind carries them away. This is a way the spiders make long-distance dispersal.
Greenville resident Nekitah Hunt said she walks out in the mornings “swinging” to avoid coming into contact with the creepy crawlers.
“Coming out the house and kicking,” Hunt said. “Once I came in, and it was like, right there in my face, and I didn’t realize it. I don’t know where they’re coming from and why they’re invading us like this, but I just want them gone.”
