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.

A study in North Carolina yielded impressive densities, tallying nearly 124 million animals per acre.
