What is the species? Is it dangerous to humans?
I chanced upon this beautiful one near our water well. It stood at a height where an adult could accidentally walk through the web and the spider would land on one's face.
As a test, I dropped a piece of leaf onto its web, and the spider jumped to action, checking what it was and it took out the leaf from its web.
Size: Web, almost circular 50 cm diameter. Spider, about 8cm.
Location: Malabar region, Kerala state, south of India
