Arthropoda, the jointed leg spineless creatures of the world, are among the most maligned of all animals. This rule is not universal, of course. Many people adore Butterflies of the Order Lepidoptera and the ancient Egyptians even worshipped the Scarab Beetle of Order Coleoptera but on the whole, when modern governments spend money on Arthropods it is to find a way of eradicating them.
Never-the-less, the "bugs" of this phylum have served an important role in the history of this planet, whether as carriers of the most devastating plagues in human history or for enabling the parallel evolution of our beautiful flowering plants.
This large group of bugs and crustacians numbers 500,000 strong by today's counts. Scientists believe that up to 10,000,000 Arthropod species are alive today.
