Insect Orders

Authored By Staff Writer | Last Updated: 12/20/2014

with so many catalogued insects in the world, it only makes sense for researchers to develop a contained system of orders.


Insect scientists (Entomologists) categorize groups of living entities as how they are related through the Theory of Evolution. In an order, there are classes, orders, suborders, families and genera, which constitute the living things that procreate with one another. More than 1 million of the categorized 2 million species are arthropods (insects/spiders).
