Kidney garden spider

Its round web always has one slice missing, like a pie with one piece taken out.

A single long thread runs through the missing slice to its leaf hideout. When an insect gets stuck, the thread shakes and the spider rushes out.

Its tummy is green underneath.

Its first name comes from the Japanese word bijo, which means beautiful lady.

The males are smaller and less colourful, and they build their own small webs near the females.
