Insects also probably have the largest biomass of the terrestrial animals. At any time, it is estimated that there are some 10 quintillion (thatâs 10,000,000,000,000,000,000 for those who like actual numbers) individual insects alive. In the United States, the number of described species is approximately 91,000.
There are more than one million species of animals (Kingdom Animalia), more than all the other kingdoms combined. More than half of all animal species are insects (800,000 species), and beetles (300,000 species) comprise the largest order of insects (one fifth of all species--using a total of 1.5 million).
