Joro Spiders: The Vibrant and Large Invasive Orb-Weaver Species Making Its Way Across the United States

A large, vibrant yellow and black spider species known as the Joro spider has been making its way across the United States, particularly in the Southeast and East Coast regions. This invasive orb-weaver species, native to East Asia, has been causing quite a stir due to its size and unique characteristics.

The Joro spider is an invasive species that can span up to 8 inches when fully grown. They have bright yellow and black coloring and are most commonly seen in August and September. These spiders use a tactic called 'ballooning' for young spiders to travel using winds and electromagnetic currents of the Earth.

Despite their size, experts assure that Joro spider bites are not deadly or medically relevant to humans. However, they might cause an allergic reaction or itch in some individuals.

Joro spiders have been reported in various states including Georgia, South Carolina, North Carolina, Tennessee, Oklahoma, West Virginia, and Maryland. Researchers from Clemson University determined that Joro spiders can withstand freezing conditions better than golden silk spiders due to their higher metabolism and heart rate.

Joro spiders do not have wings but can sail on wind currents using their silk as a balloon. Adult female Joro spiders are most commonly seen in August and September. Their webs can span up to 10 feet, making them a sight to behold.

Despite the hype surrounding these spiders, experts advise that there is no need for alarm as they do not pose a threat to humans or pets. However, their arrival may impact native spider populations and ecosystems.

It is important to note that while Joro spiders are an invasive species, it is crucial to avoid spreading misinformation and fear. Always rely on credible sources for information.

  • Unique Points
    • The Joro spider is an invasive orb-weaver species native to East Asia.
    • Joro spiders have bright yellow and black coloring and can grow up to three inches long when their legs are extended.
    • Joro spiders use a tactic called ‘ballooning’ for young spiders to travel using winds and electromagnetic currents of the Earth.
    • Joro spiders eat insects that land in their web and might compete with native spiders for food.
    • Adult Joro spiders are most commonly seen in August and September.
    • Joro spider bites are not deadly or medically relevant to humans, but they might cause an allergic reaction or itch.

  • Fallacies (95%)
    The article contains an appeal to authority fallacy when the authors quote experts expressing their opinions on the Joro spider. However, this does not significantly impact the overall content of the article as it is used to provide context and expert insight. No other fallacies were found.
    • My sense is people like the weird and fantastic and potentially dangerous,” said David Nelsen, a professor of biology at Southern Adventist University who has studied the growing range of Joro spiders. 'This is one of those things that sort of checks all the boxes for public hysteria.”
    • But the shy critter poses little risk to humans. Instead, Burrack said, introduced pests like fruit flies and tree borers can do more damage.
    • They’re probably not going to get that far in a single year. It’s going to take a bunch of incremental steps.”

  • Unique Points
    • Joro spiders can live in surprising places like traffic lights above busy intersections.
    • Joro spiders react differently to stressors than other spiders and remain still for long periods when disturbed.
  • Accuracy
    • Joro spiders can have large webs up to 3 feet wide for a single spider and up to 10 feet wide for a cluster.
    • Joro spiders are able to survive in various conditions, including urban areas.
    • It is unpredictable when Joro spiders will arrive in the Northeast as their movement is random.
    • Adult Joro spiders do not fly but baby spiders have an ability to balloon and hitchhike on cars or planes.
    • Joro spiders are relatively harmless to humans but can decrease native spider populations when they become abundant in an area.
    • More research is needed to determine the long-term effects of Joro spiders on ecosystems.

  • Fallacies (95%)
    The article contains one instance of an appeal to fear with the statement 'They are invasive, and Nelsen's research has shown that when a lot of Joro spiders live in an area for a long time, native spider populations decrease.' However, this statement is not presented as a fallacy by the author and is supported by evidence provided in the article.

    • They are currently found in North Georgia, the Appalachian region of South Carolina, the far west corner of North Carolina, and the far southeastern corner of Tennessee.
    • Despite their size, experts say they are harmless to humans and pets. Bites from the spider would cause mild discomfort similar to a mosquito bite or bee sting.
