Insects are animals with a very high adaptation rate. The fossils can be traced back to Ordovicius. Fossils of primitive giant cockroaches and dragonflies have been found. A number of Diptera members such as flies and mosquitoes trapped in sap were also found.
Metamorphosis on Insects Edit
This animal is also a classic example of metamorphosis. Each insect undergoes a process of shifting from an egg to an adult form ready for reproduction. This phase change of body shape is often very dramatic. In each stage there is also a process of "skin change" commonly called the pelungsungan process. These stages are called instar. Insect orders are often characterized by their type of metamorphosis. Metamorphosis in insects is 2, namely perfect metamosphosis and imperfect metamorphosis. The striking difference in perfect metamorphosis is the formation of a cocoon, whereas in imperfect metamorphosis there is no stage of cocoon formation.
Insect morphology Edit
In morphology, the body of an adult insect can be divided into three main parts, while the pradatical form usually resembles its ancestor, a soft-looking animal like a worm. The three body parts of adult insects are the head (caput), chest (thorax), and abdomen.
Role of insects Edit
Many insects are beneficial to human life, such as decomposing organisms and decomposers including waste decomposers, as aesthetic and tourist objects such as butterflies, colorful beetles, beneficial to pollination and as a pest of plants, valuable animal feed (birds) high economy [10], producer of honey (from the genus Apis) etc. [11]. Besides the direct role of insects also has an indirect role of maintaining an ecological balance in nature, since insects are one of the food chains, where several species of birds make insects the main food. But if the numbers are out of control due to the disturbed nature balance due to the reduced predators of insects, the number of insects will be out of control, because one of its properties can multiply rapidly, so it will also be detrimental to agriculture, plantation, to humans directly . Some areas make some locusts as foodstuffs, such as wooden locusts, some beetle larvae are also consumed as delicious food. the nutrient content of grasshoppers rich in animal protein content even in hongkong, thailand and some European countries some star hotels have provided a menu of locusts.
Insect foodSharing
Food on insects depends on the type of mouth, there are several types of mouth types in insects which will also determine the type of food they are: piercing sucking, biting chewing, kissing. in the world of insects there are several types of food that are often found, namely insects of herbivores, carnivores and there are also omnivores.
