Ukweli

Females spin webs several metres long, and their yellow threads look gold in sunlight.1

The name comes from a shape-shifting spider in Japanese folklore that can breathe fire and control other spiders.1

By October 2022, its range covered at least 120,000 km² across several US states.1

In the Ao-Naga people's food tradition, this spider is eaten.1

The spider was first spotted in North America in Hoschton, Georgia, in 2013, and its presence was confirmed in 2014.1

Smaller males are sometimes seen in the females' webs during autumn, when they mate.1
