Beetles are the most numerous and successful life forms on the planet. They have been around since the Jurassic, 200 million years ago. Today, they live on every part of the planet except Antarctica and the tops of the tallest mountains. Over 350,000 species of beetles have so far been identified, representing over 20% of all known life forms. Estimates for the number of unidentified species range into the millions.
