GOLDEN BEETLES



Got the gold bug? Golden animals are both beautiful and rare, much like the precious metal itself.


Certain types of beetles can appear so golden it’s hard to believe they haven’t somehow incorporated 24-carat gold into their gleaming shells! They haven’t – if they did, human treasure hunters would have long since driven them to extinction. Among the most golden of these “gold bugs” are the Golden Scarab Beetle and the Golden Tortoise Beetle.


These insects get their golden appearance using some pretty sophisticated science. The Golden Tortoise Beetle can adjust the moisture content between two layers of its wing covers, resulting in varying levels or golden iridescence as seen by the human eye.
