Why do insects have the highest number of species?
There is evidence that the species richness of insects has been enhanced by: (i) their relative age, giving time for diversification to take place; (ii) low extinction rates. There is little evidence that rates of origination have generally been high or that there are limits on numbers of species.
Which insects have the most species?
It hardly comes as a surprise that ants are the most numerous insect in the world. These colonial hymenopterans may number from 10-100,000 trillion individuals globally; there are more than 10,000 species.

Are insects the largest group of animals?
Insects are the largest and most diverse group of organisms on Earth. There are approximately 30 orders with the number of described species reaching nearly 1 million. These phenomenal creatures constitute about 75% of all described animal species and are incredibly abundant, yet abundantly overlooked.
What is biggest insect in the world?
The tree weta is the world’s heaviest adult insect; the larvae of goliath beetles are even heavier. This endangered member of the cricket family is found only in New Zealand and can weigh as much as 2.5 ounces; that’s the size of a small blue jay. (Here’s a weta sticking up for itself against a cat.)
Why insects are the most diverse group of animals?
Because Insects Have Been Here Longer. Scientists show that many insect groups like beetles and butterflies have fantastic numbers of species because these groups are so old. In contrast, less diverse groups, like mammals and birds, are evolutionarily younger.
Which insect order has the most insects?

Why are insects the most diverse and abundant group in the animal kingdom?
How many insects are there in the United States?
The largest numbers of described species in the U.S. fall into four insect Orders: Coleoptera (beetles) at 23,700, Diptera (flies) at 19,600, Hymenoptera (ants, bees, wasps) at 17,500, and Lepidoptera (moths and butterflies) at 11,500. Several enlightening studies have been conducted involving the numbers of individual insects in a given area.
Why are there so many species of insects?
These great numbers of insect species and individuals were created by a number of factors including their long geological history, the capability of flight, their small size that allows survival in many various habitats, their ability to store sperm for delayed fertilization, and their general adaptive abilities to the environment.
How many insects are there in an acre?
Even specific insect species have been found to be quite numerous, with calculations of from 3 to 25 million per acre for wireworms (larvae of click beetles). Certain social insects have large numbers in their nests. An ant nest in Jamaica was calculated to include 630,000 individuals.
What is the population potential of an insect?
To appreciate the population potentials of insects the example of the housefly is sometimes used, stating that the descendants of one pair of this insect, provided that they all survived during a five month season, would total 190 quintillion individuals.
