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 800,000 species of insects on earth, more than all the other plants and animals combined. Of this great number of insects, nearly half are beetles. Unlike other insects, beetles have a pair of leathery protective wings called elytra that cover their membranous flight wings. During flight, the elytra are spread apart and the two flight wings are unfolded and extended.
