Northern Georgia has seen an invasive species bomb their communities. The Joro spinNative to East Asia, it spins its web across porches, power lines, gardens, and vegetable patches everywhere you look. Technically, the joro spiders in Georgia, other than the web, have not yet done any direct damage to these ecosystems. But they have become a major nuisance.
Analysts estimate that there could be millions of creatures right now with the potential for population growth and expansion to other parts of the country.
What’s happening in Georgia?
The spread of the Joro spider has blown up and even propelled social media people to isolate themselves in their homes. In metro Atlanta, residents are stunned and stunned. They accidentally come upon a Joro’s golden webs, especially along the Chattahoochee River.
Homeowners find populations thriving in their gardens and trees or making beautiful homes in their basements and crawl spaces. A homeowner discovered that his porch was suddenly overtaken by Joro webs at least ten feet deep. That same homeowner says he killed more than 300 of the invasive species on his property. The year before, he had treated only a few dozen.
The infection is already spreading. The creatures move to south carolina and the population is expected to continue to spread south. The species seems to ignore the natural flows inward spider communities. These are often linked to local conditions, such as changes in rainfall.
There is a theory that the Joro spider thrives in Georgia due to its climate similar to the spider’s native Japanese environment.
Are Joro spiders a threat?
Aside from the idea of how easily an invasion of creepy crawlies can overwhelm a community, the invasive species actually poses no risk to humans or pets. The spiders have the ability to bite. But their bite is too small to even break the skin. The venom they use to paralyze their prey is not strong enough to harm larger animals. There is a chance of an allergic reaction.
But as the population grows, researchers have yet to agree on the impact these spiders will have on other species and the environment.
There are people who tend towards positivity. Entomologists point out how Joros feeds on unwanted insects, oppressing the population of yellow jackets, corrosive to flys, and mosquitoes. The invasive species is also a natural predator of the marbled brown stink bug, a significant threat to Georgia’s crops and homes.
Still, the scientific community agrees that no assessment of the impact of the Joro spider should be accepted too quickly. They want more research. A team at Clemson University in South Carolina says it’s too early to determine if there is any negative connotation to this non-native and invasive species in South Carolina’s ecosystems.
Meanwhile, the people of Georgia are dealing with the scale of the growing invasion. Naturalists and garden enthusiasts want to learn more about these arachnids, especially how they will affect other native spiders, bees and other pollinators. The Joro makes larger pollinators part of their diet, but the Joro will need more food sources.
Joro spiders can compete with others orb weavers for food or operate like some spider species, with native spiders feasting on food caught in their webs. There are simply too many unknowns to estimate what may come next. The only thing they can reasonably agree on is the likelihood that they will return in greater numbers in the coming years.
How this all started
The University of Georgia says the first sightings of the invasive species in the state were sometime between 2013 and 2014. In 2015, genetic analysis confirmed the sightings as the Georgia Museum of Natural History tracked the spread.
Now this invasive species is new. The Joro spider is native to Asia and was only discovered there a decade before showing up in Georgia. There’s no documented reason why these spiders — which already cover vast swaths of eastern Asia — have come to Georgia. The best bet is that the invasive species piggybacks on the United States via a sea container. Somehow they even narrowed that down to a container dropped off in the Braselton area along I-85.
Since the initial discovery, the community’s size has grown in extreme numbers, reaching more than two dozen counties in Georgia. Soon, the crawlers would be sighted in South Carolina. The animals seem to gravitate towards riparian states and urban areas, usually around houses. They also like to search deep in wooded areas.
Scientific communities suspect that Mother Nature could eventually balance things out, bringing the burgeoning number of Joros back to normal.
An overview of the Joro Spider
No threat to anything but its natural food, encountering the Joro spider is more of a nuisance than anything. Unlike many spiders that spin flat webs, the invasive species create nearly three-dimensional webs. They are also orb weavers, meaning that their wheel-shaped webs are not grayish white but shiny gold. The orbits can be large and multi-layered. You run into them all the time and people say they are sticky and hard to remove.
Females drop sacs of between 400 and 1500 eggs. Compare that to the average native species that lays 200 to 500 eggs and you see how fast the population can grow. Once the eggs hatch in the coming spring, the young hitchhike or ride along on a silk strand, landing and expanding into new habitats.
The Joro male has a brown body. It is the female that stands out with her bright blue, yellow and red markings covering their dimensions. What is really distracting is that the Joros can measure a diameter of more than five centimeters with outstretched legs. The average hou
se
spider, on the other hand, is no more than 5/16 of an inch in length.
Prey & Predators
One benefit most scientific community attributes to de Joro is the impact the spiders have on pests. They like brown stink bugs. The native spider does not eat them and the stink bug is a major threat to local agriculture. Joro spiders also feast on mosquitoes and yellow jackets. Another nice thing that has been noted is that the invasive species don’t seem to crowd out native spiders.
When it comes to predators, the Jorospin is fodder for wasps and mud scrapers.
