Insects make up the vast bulk of species diversity on the planet. Many millions of insect species exist and entomologists have divided them into a manageable number of units called Orders. The members of each insect Order have arisen from a common ancestor, share similar structural characteristics and have certain biological attributes in common.

Not all insect Orders are equal in species number; some Orders have just a few hundred species while others have more than 100,000 species. The range of structural characteristics and biological features tends to be broader in the more species-rich Orders.

Predictions about the biology, behaviour and ecology of an insect can be made once you know its Order. But how can you know the Order to which an insect belongs? Insects can be identified in various ways. Comparing a specimen with a book of illustrations of identified insects is one way. Using a printed key is another way. This Lucid Mobile based identification key combines the advantages of these methods and adds a new dimension of simplicity and power to the process of identification.
