Beetles are a type of insect that enters the Coleoptera order. The origin of the word coleoptera comes from the Greek word coeleos which means a veil and pteron means wing. So that it can be concluded that insects have a hood on their wings.
Beetles are the most species of insect species, there are around 350,000 species. And even beetle species continue to grow year after year. If total can be estimated species described and not described can reach 5 and 8 million.
The beetle has wings that are hard and thick enough to function as a rear wing cover and protect the body. The front wing is called elitron.
When flying only the rear wing is functioning. While the front wing does not work. The beetle mouth has a reliable type of bite and chewer. Likewise, the beetle head can be moved forward and back freely so that it can turn into a snout.
Beetles have a pluralistic eye and without a single eye. In the abdomen there are 10 segments and only part of the sternum is visible in the sternum.
If carefully considered, prothorax and mandible found in male beetles can be enlarged which is used to fight with fellow beetles or as self-protection from other insects.
Beetles can live in all habitats, except in the polar regions and the sea. They can and can survive by adjusting to the living ecosystem.
They can consume from plants and fungi. And there are also some of their types that are useful for agriculture, for example potato beetles, cotton beetles.
