Asian Golden Tortoise Beetle

Description:

A small perfectly shaped circle. About as big as my thumbnail. 1x1cm? Metallic orange, yellow, green! Its "shell" was hard. When it decided to move, it moved quite quickly.

Habitat:

At the border of a jungle area, next to the road, Phuket Thailand.

Notes:

I was walking up a hill when my eye fell on something shiny in the sun. I stopped because it looked extremely out of place. At first I thought somebody had lost a shiny button and nearly wanted to continue walking, when something in me told me to have a closer look. WAUW! I could not believe it was alive untill it started to move!!! What an amazing little bug! Anyone knows what this is PLEASE!
