Very sadly I have been unable to find any amazing facts about carpet beetles. However, I have found these great facts about beetles in general:
One out of every four animals on Earth Is a beetle. Beetles are the largest group of living organisms known to science, bar none. Even with plants included in the count, one in every five known organisms is a beetle. Scientists have described over 350,000 species of beetle, with many more still undiscovered. By some estimates, there may be as many as 3 million beetle species living on the planet.
Most adult beetles wear body armour. One of the traits that make beetles so easy to recognise is their hardened forewings, which serve as armor to protect the more delicate flight wings and soft abdomen underneath.
Beetles have been around for about 270 million years. The first beetle-like organisms in the fossil record date back to the Permian Period which was roughly 270 million years ago. True beetles — those that resemble our modern-day beetles — first appeared about 230 million years ago. Beetles were already in existence before the breakup of the supercontinent Pangaea, and they survived the K/T extinction event thought to have doomed the dinosaurs.
