The joro spider, a large spider native to East Asia, hangs in its web in Johns Creek, Ga., on Oct. 24, 2021.ATLANTA — A large spider native to East Asia has spun its thick, golden web on power lines, porches and vegetable patches all over north Georgia this year — a proliferation that has driven some unnerved homeowners indoors and prompted a flood of anxious social media posts.
The Joro — Trichonephila clavata — is part of a group of spiders known as orb weavers for their highly organized, wheel-shaped webs. Common in Japan, China, Korea and Taiwan, Joro females have colorful yellow, blue and red markings on their bodies. They can measure three inches across when their legs are fully extended.
Cushing and other experts say Hudson said a researcher collecting them with her bare hands reported the occasional pinch, but said the spiders never broke her skin. Turpin, 50, tried to set a Joro spider web on fire at her East Cobb home, but then got scared it would fall on her and fell into a hole as she quickly backpedaled. She had a neighbor remove it instead.Nancy Hinkle, another entomologist at the University of Georgia, said Joros help suppress mosquitoes and biting flies and are one of the few spiders that will catch and eat brown marmorated stink bugs, which are serious pests to many crops.
