The Joro spider, scientifically named Trichonephila clavata, originates from East Asia. It has been slowly migrating northwards and may expand into Canada and northeastern US in the coming years.
Joro spiders can have a span of 8cm to 20cm with yellow bodies for females and muted yellow/black colors for males. They use a technique called ballooning to ride wind currents, enabling them to travel long distances.
Research in 2022 found Joro spiders have a high metabolism and heart rate, aiding survival in colder climates. Their arrival in the US could impact local ecosystems.
The Joro spider's potential spread north is attributed to various factors, including their ability to survive in colder climates, use ballooning for long-distance travel, and high metabolism rate.
