New research, published Feb. 17 in the journal Physiological Entomology, suggests that the palm-sized Joro spider, which swarmed North Georgia by the millions last September, has a special resilience to the cold.
This has led scientists to suggest that the 3-inch (7.6 centimeters) bright-yellow-striped spiders — whose hatchlings disperse by fashioning web parachutes to fly as far as 100 miles (161 kilometers) — could soon dominate the Eastern Seaboard.
“People should try to learn to live with them,” lead author Andy Davis, a research scientist at the University of Georgia, said in a statement. “If they‘re literally in your way, I can see taking a web down and moving them to the side, but they‘re just going to be back next year.”
