1. What Exactly Are Joro Spiders?
Joro spiders (Trichonephila clavata) are large, colorful arachnids native to East Asia. These spiders have gained attention due to their increasing prevalence in the southeastern United States. Understanding their characteristics and behavior is crucial for pet owners.
1.1 Origin and Spread
The Joro spider, originating from East Asia, was first identified in the United States in 2014 in Georgia. They have since spread to other southeastern states, including South Carolina, North Carolina, Tennessee, and Alabama. According to research from the University of Georgia, their rapid spread is due to their ability to use wind to disperse, a behavior known as “ballooning.”
1.2 Physical Characteristics
Joro spiders are known for their impressive size and striking colors:
- Size: Females can grow up to 3-4 inches in leg span, while males are significantly smaller.
- Color: They have bright yellow and black striped bodies with red markings on their undersides.
- Legs: Their long legs feature distinctive black and yellow banding.
- Webs: They create large, intricate orb webs that can span several feet.
1.3 Behavior and Habitat
Joro spiders typically build their webs in areas with ample vegetation, such as gardens, forests, and near buildings. They are most active during the warmer months, from spring to late fall. Their behavior is generally non-aggressive, and they prefer to flee rather than bite.
