 Globally, averages of these predictions estimate there are around 1.5 million beetle species and 5.5 million insect species with around 1 million insect species currently found and described.Between 950,000–1,000,000 of all described species are insects, so over 50% of all described eukaryotes (1.8 million) are insects (see illustration).With only 950,000 known non-insects, if the actual number of insects is 5.5 million, they may represent over 80% of the total, and with only about 20,000 new species of all organisms being described each year, most insect species likely will remain undescribed, unless species descriptions greatly increase in rate.
