The insects are arranged into orders, such as dragonflies and beetles. They undergo a radical metamorphosis, with the larval and adult stages differing considerably in their structure and behaviour. The larvae are classified into four groups on the basis of development of appendages. Beetles are insects that form the order Coleoptera, in the superorder Endopterygota.Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects.

Endopterygota, also known as Holometabola, is a superorder of insects within the infraclass Neoptera that go through distinctive larval, pupal, and adult stages. Sharp (1898), the marked divergence among the Hexapoda, as regards life-history, is between insects whose wings develop outside the cuticle (Exopterygota) and those whose wings develop inside the cuticle (Endopterygota), becoming visible only when the casting of the last larval cuticle reveals the pupa. Examples: Belostoma, Aphids, Cicadas, scale insects. They are distinguished from the Endopterygota (or Holometabola) by the way in which their wings develop. Frog is the best example of this. Insects are invertebrate animals of the Class Insecta, the largest and (on land) most widely distributed taxon within the Phylum Arthropoda.Insects comprise the most diverse group of animals on the earth, with over 800,000 species described—more than all other animal groups combined.

However, while the fossil history of the various insect orders is becoming fairly well known in a gross sense . These and many more examples underscore the pharmacological diversity of insect-derived bioactive substances and their potential There are many more Endopterygota than there are Exopterygota. You will need a good hand lens to observe some of the smaller parts of the insect, for example to count the number of segments in the tarsi, or to have a close look at the antennae. I would like to have the taxon 'Endopterygota' for all holometabolous insects. insect - insect - Annotated classification: Class Insecta Body divided into head, thorax, and abdomen; head with 1 pair of antennae, mouthparts consisting of a pair of mandibles and 2 pairs of maxillae, the 2nd pair fused medially; thorax with 3 pairs of legs and usually 1 or 2 pairs of wings; segmented abdomen lacks walking appendages; genital opening near anus; metamorphosis usually occurs .

In winged insects the adult differs in several respects from the young, such insects are said to undergo metamorphosis in becoming adults. For this reason, they are also known as Endopterygota (from Latin endo-= "inside" + pteron="wings"). The one I have followed here and throughout these pages is adapted from that used by the online database Catalogue of Life - and is a basically functional, if not extremely up . The class Insecta is divided into 2 subclasses: Apterygota,or wingless insects, and Pterygota, or winged insects. Types of Insect Larva The larva is a general term to denote young one or immature stage of insect between egg and pupa having complete and hyper metamorphosis (Holometabolus or Endopterygota insects). Creating this in the current system has its difficulties, because its rank does not have a name - it would be integrated slightly above 'Order'. This is called . There are imaginal discs for Wings, legs, eye and other structures in larva of holometabolous insects.
