If you live in Georgia, it's hard not to notice the state's latest resident.
The bright yellow, blue-black and red spiders' golden webs will be all over power lines, in trees around town and even on your front porch come summer.
The Joro spider first arrived stateside around 2013 and has since spread across the state and Southeast. But new research from the University of Georgia suggests the invasive arachnids could spread through most of the Eastern Seaboard of the U.S.
There's really nothing we can do to stop them. But that's not necessarily bad news.
Joros don't appear to have much of an effect on local food webs or ecosystems, said Andy Davis, corresponding author of the study and a research scientist in the Odum School of Ecology. They may even serve as an additional food source for native predators like birds.
"People should try to learn to live with them," he said. "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."

"The way I see it, there's no point in excess cruelty where it's not needed," added Benjamin Frick, co-author of the study and an undergraduate researcher in the School of Ecology. "You have people with saltwater guns shooting them out of the trees and things like that, and that's really just unnecessary." READ MORE...
