Insect scientists - or Entomologists to be more precise -
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, or insects (and spiders).
