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.
Scientists estimate there may be as many as 10 - 30 million unidentified insect species, many of them living in the rainforest, and up to 1 million mite species. Mites are small arthropods, a group of animals related to, but not the same as, insects.
