THE LITTLE THINGS THAT RUN THE WORLD

The classification of insects can be complex but it is very important to group and identify insects so that they can be studied reliably. Insects, like all animals, are classified using a hierarchical system of classification

THE FASCINATING FACT

It has long been recognized and documented that insects are the most diverse group of organisms, meaning that the numbers of species of insects are more than any other group. In the world, some 900 thousand different kinds of living insects are known. This representation approximates 80 percent of the world's species.Insects also probably have the largest biomass of the terrestrial animals. At any time, it is estimated that there are some 10 quintillion (10,000,000,000,000,000,000) individual insects alive.

​

Recent figures indicate that there are more than 200 million insects for each human on the planet! A recent article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans.

(Sub Class)
Apterygota
The Apterygota, which formerly included the other primitively wingless insects currently placed in the class Entognatha, are now restricted to the two orders Archaeognatha and Zygentoma, which in turn were formerly united as the Thysanura.

(Sub Class)
Palaeoptera
Primitive winged insects, with their wings held upright or outstretched at rest and incomplete metamorphosis.

(Sub Class)
Polyneoptera
Winged insects, with a broad, fan-like extension to their hind wings, and incomplete metamorphosis.

(Sub Class)
Paraneoptera
Higher insects, with mostly incomplete metamorphosis, where a nymph generally resembles the adult.

(Sub Class)
Endopterygota
Higher insects, with a clear metamorphosis from larva via a pupa to adult, also called Holometabola.
