These insects belong to herbivorous insects or plant-eaters called NPFs. A mouthpiece of a bite-chewing type, generally the mandible develops well. In some species, especially of various types of mouth tools are formed on the muzzle formed in front of the head. The type of leg that gives birth: saltatorial that works to jump. Experiencing Perfect Metamorphosis (holometabola) The development through stadium: egg -> larva -> cocoon (pupa) -> adult (imago). Larvae generally have thoracal legs (oligopods), but some are not legged (apoda). Cocoon is not important from rest (break) and liberate / free type. Examples of these insects are horn beetle (Oryctes rhinoceros), grain lice (Rhyzoperta dominica), coconut leaf beetle (Brontispa longissima Gestr) and so on. 
One of the order of insects that will rotate this time is the insect Coleoptera order. The most famous species of this order are the beetles. Beetles are animals that have the usual appearance of insect species. Forty percent of all insect species are beetles (about 350,000 species), and new species are still commonly found. Estimates estimate the total number of species, described and not described, between 5 and 8 million (Suhara 2009). The Order of Coleoptera, taken from the word coeleos which means wasteland and pteron which means wings. Coleoptera is an insect that has a sheath on its wings .. 
What are the members of this order? Its members are referred to as plant pests and some are also called predators for other insects. The wing-looking morphological features consist of two pairs. The front wing is hardened and thickened and has no wing veins and is called elytra. At rest, elytra seems to be divided into two (split right in the middle of the dorsal part). The wings are membranous and when the break is folded under the front wing. 
Insect populations are abundant in the world. Almost 75% of the skin that lives on earth is an insect. Insects have a strong sense for the environment. There are different types of insects, there are beneficial insects and also parasitic insects. Beneficial insects can act like soil aeration, help pollinate flowers, control insect pests, decompose organic materials and so forth.
