They look almost manufactured. Many tortoise beetles have transparent cuticles, the tough but flexible outer covering which gives the insect family its name protects the delicate creature within.
The living tissue is often metallic in color and can in some species even change color. The combination is as diverse as it is extraordinary - many look like tiny robots assembled to infiltrate, the ultimate bug. Take a look in at the amazing variations of tortoise beetle our world holds.
