Meet the Joro
Big, bright yellow, and settling into city life.
Trichonephila clavata, native to East Asia.
How to spot one
- Females: yellow and blue-gray banded bodies
- A red patch underneath
- Golden webs, often strung across porches and eaves
Why they spread
In spring, young Joros balloon on silk threads to new spots. They tolerate cold, traffic noise and city life.
Should you worry?
Mostly a nuisance, not a danger.
Their bite is rarely an issue, experts say.
