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.
Recent figures indicate that there are more than 200 million insects for each human on the planet! A recent article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. Selected References: Erwin, T. L. 1983.
