Beetle (coleoptera)

Beetles are a group of insects that make up the order of Coleoptera. The word coleoptera comes from the ancient Greek κολεός, koleos, and πτερόν, pteron, which when both are united means the wings are sheathed, since most beetles have two pairs of wings. The wing couple in the front is called elytra. These wing pairs are hardened and thickened which can protect the wing spider behind it and also protect the back of the beetle's body.

The Order of Coleoptera has more species than any order. The largest taxonomic family, Curculionidae, is also included in this order.

The spread of beetles is very wide. Beetles can be found in all major habitats, except in the oceans and polar regions. They interact with their ecosystem in various ways. Some beetle species are the producers of detritus, by destroying dead animal and plant tissues, eating certain types of carcasses, and consuming waste. Some species eat mushrooms. Some species are flower and fruit eaters. There are also species that are parasites or parasitoids. Some other species are predators or predators for other invertebrates. Many species of predatory beetle are important as agricultural pest control. For example, beetles in the Coccinellidae family that prey on aphids, scaly insects, thrips, and other plant-sucking insects that can cause crop damage.

Horn beetle has features in the form of eyes that are on the left and right of the head. His eyes are compound eyes consisting of 20,000 individual eyes. Other body functions, ie antennas used to smell or foraging. Beetles have three pairs of legs that have hooves like hooks to climb trees.
Beetles undergo perfect metamorphosis, from eggs to adult animals. After the eggs hatch, the larvae undergo three times the transformation period. The larvae eat so much to gather energy.

The cocoon house is underground, has a vertical round shape because it makes it easy to get out of the ground. The first time the beetle came out of the cocoon, it was still very soft. They waited until his body became hard. After the process then the beetle appears to the ground. Adult beetles can survive for two to six months

The uniqueness of the beetle can be seen from the physical form that has a hard wing. The wing is used to fly and protect the body parts of beetles from various weather and enemy attacks. In addition, some types of beetles also protect themselves from the threat of the enemy by turning his body and pulling his legs inside. The way it aims to fool the enemy so that the beetle looks dead.

With many species of beetles, there are various sizes of beetles ranging from the smallest size of 0.25 mm to the largest reaching up to 20 cm long.

The uniqueness of the beetle is also present in its function. Although it is considered a plant-destructive insect, but the beetle can be useful in the process of pollination of plants and can be used as food when the beetle is still in the form of larvae. Protein content in beetle larvae is believed to meet the protein and nutrients needed by the body.

The uniqueness of the beetle lies in its life cycle. Beetles undergo complete metamorphose because their life cycle begins with eggs, becomes larvae, larvae becomes pupae and eventually develops into adult beetles. Before becoming an adult beetle, the beetle undergoes several cycles first. Even at the time of the cycle process, the beetle that spawns on the sago tree will form the larva commonly known as sago worm. Sago caterpillars live on sago trees and are usually taken for consumption by the surrounding community.

The uniqueness of the beetle is also found in the body color is diverse. Not only black or brown it turns out the beetle has many colors depending on the type of species. The colors on the beetle will look beautiful and beautiful so it makes many people curious to have it as a decoration. Hornbill beetle is one of a kind of unique beetle even often diperjuabelikan as pets. Its unique shape has a horn to make many people interested and want to make it as a pet.

There are types of beetles that can play a major role in the balance of ecosystems on earth because of the beetle's ability to recycle natural nutrients and this activity is usually done by a dung beetle.

The uniqueness of beetles is also found in one type of beetle, the beetle koksi or commonly referred to as a ladybug. Ladybugs have a unique way of eating because it uses a pair of lower jaws to hold the prey then pierce its prey with a special tube in the mouth. At the time of the injection, the beetle enters the digestive enzyme into the body of its prey to extract the tissue fluid from the body of its prey
