If you think that flying beetles are bugs, you are wrong. Beetles and bugs are two different types of insects. In all, there are over a million of different species of insects that have been identified, and it’s speculated that there may be up to ten million species overall. Nature is so huge that we are still identifying new insects, animals, and fish every year.Beetles are a large group of insects, the biggest one of thirty-two different orders. Beetles make up the order Coleoptera, which consists of 125 families of beetles and approximately 500,000 species. Because the order is so large, scientists report that one out of every four species of animals in the world is a beetle.
