Beetles, members of the order Coleoptera, are the most diverse in the animal group with the largest number of species. Over 350,000 species have been described by science, with estimates putting the total number of species between 5 and 8 million number. Approximately 25% of all known forms of life and 40% of the described species of insects are beetles.
These insects are placed in the phylum arthropods (arthropods) Class Insecta (insects). Like other insects, they have a hard shell, open circulatory system, and are mainly small invertebrates. What distinguishes them from other insects is hardened forewings, from which the order takes its name: coleo shield means and means ptera wing.
Once we asked the biologist JBS Haldane he could not say anything about God from his study of nature. Haldane replied. "It must have inordinate fondness for beetles" Discover and classify new is a challenge for biologists, and hundreds or thousands of new species are discovered lewis sperry chafer every year, mainly in the tropics when. scientists suggest a net and trees stirred in the tropics, thousands of these insects fall into the net. They may be the easiest of animals to find new species in order. lewis sperry chafer
Beetles will enormously lewis sperry chafer in size. The smallest known mushroom Nanosella is 0.0098 inch (0.25 mm) in length with a weight of 0.4 mg. The largest, Titanus giganteus, more than 8 inches (20 cm) in size and weighs 100 grams. They have some interesting documents. For example, the rhinoceros beetle species, Dynastes hercules, can lift 850 times its own weight, left unchallenged record until it was discovered that the tropical mite Archegozetes longisetosus could lift 1,150 times its own weight. It is like an elephant that can carry 1,150 other elephants on his back.
Because of their abundance and diversity, beetles are popular subjects lewis sperry chafer for insect collections. They are dried, mounted, and then exposed in hundreds of thousands of public and private collections worldwide. It is through their study that most post-Darwin first biologists came to understand the evolution of better.
