Trichonephila clavata, commonly known as the Joro spider, is a large orb-weaver spider native to East Asia. It is recognized for its vibrant yellow and blue-black banded legs and intricate web patterns. These spiders thrive in forests and gardens, often seen hanging in their golden webs. Notably, females are significantly larger than males and are known for their striking coloration and impressive web-building skills.

Trichonephila clavata, commonly known as the Joro spider, is native to East Asia. It is primarily found in countries such as Japan, Korea, China, and Taiwan. Recently, it has also been identified in the southeastern United States, particularly in Georgia and South Carolina, due to accidental introduction.

The Joro spider typically inhabits temperate and subtropical regions, thriving in environments with high humidity and moderate temperatures. It is often found in forests, gardens, and human-influenced areas such as parks and urban green spaces.

Trichonephila clavata occupies the ecological niche of an arboreal orb-weaver spider. It constructs large, intricate webs between trees or shrubs to catch flying insects. This species plays a role in controlling insect populations and is an important part of the local ecosystem's food web.
