Please don’t worry about this giant golden spider

Native to East Asia, Jorōs are one of many so-called golden globe weavers, named for the shiny silk they use to spin webs (which, by the way, can be up to 10 feet wide). the spider was first discovered in the US by scientists in Colbert, Georgia, in 2014, although local accounts suggest it may have appeared several years ago. Colbert is close to a warehouse and distribution center, so it’s likely the spider arrived by accidently hitchhiking on an international freighter.

In 2020, Joro’s population skyrocketed. Scientists believe they mainly disperse through a technique called ballooning: Spiderlings climb high, release webs, and glide along air currents to reach their next destination. That’s when the spiders first caught the attention of the media. A second wave of news came with the discovery that, unlike the native orb weavers, the Jorō could tolerate colder climates. Several articles mentioned palm-sized parachute gyros that will soon fly to the East Coast. Others see them as a positive — perhaps Jorōs will hunt harmful invasives, like bugs, and stop them. But neither of these has been proven true.

“There is a strong temptation to label them as good or bad,” said cosmologist Angela Chuang of the University of Florida, who co-authored the paper. “But we still don’t know enough to tell.” by Chuang previous job found that 47 percent of all spider news was inaccurate, containing misidentified images or factual errors about their anatomy and venom toxicity. Additionally, 43 percent of the articles overstated, exaggerating the size or ruffles of spiders and linking them to trigger words—like scary, nightmareand Deadly—that can promote arachnophobia.

negative insurance distorted perception about the risk spiders pose to humans and shape people’s decisions about wildlife protection efforts. At worst, sensational accounts lead to loss of money and resources: Spider sightings caused unnecessary school closures and directed everyone to extreme measures of eradication. Increasing pesticide use (which is only a temporary solution, Coyle says) can hurt homeowners financially as well as nearby flora and fauna.

On the other hand, Coyle says, over-reporting is also dishonest, because it can lull the public into a false sense of security before scientists thoroughly assess the economic effects. and the environment of a new species.

The reason it’s difficult for scientists to predict the future is that arachnids’ invasions are largely understudied. Unlike insects, they are not agricultural pests, so monitoring for invasions is less of an economic priority. Most are also harmless. “The vast majority of spiders pose no threat to humans and do a lot of good,” said Catherine Scott, a behavioral ecologist at McGill University. They are essential predators that help maintain equilibrium in most terrestrial ecosystems.

But most experts concede that Joros must have some especially due to their rapid population growth. Today, they span an estimated 46,000 square miles (120,000 square km), most concentrated in northern Georgia—although a few have been discovered as far north as Washington, DC and as far back as Washington. west like Oklahoma. “There’s no way it’s conceivable that they’re constantly entering the ecosystem without causing some ripples,” Coyle said. His hunch, based on some preliminary survey work, is that Jorōs will likely push out smaller native spiders, which could have a further stratifying effect in the food chain. There is also little chance they can run out pollinator population very important for high crop yield if too many bees and butterflies get caught in their webs.
