In the United States, the number of described species is approximately 91,000. The undescribed species of insects in the United States, however, is estimated at some 73,000. 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 ...

Insects belong to Subphylum Hexapoda in Insecta Class. The invertebrates are characterized by having 3 body segments namely the head, the thorax, and the abdomen. Common insects have six legs, a pair of antennae, compound eyes and an exoskeleton. Almost all insects reproduce by laying eggs which metamorphosize through several stages to become adult...
Conservative estimates put the number of species at two million but can be as high as 30 million. However, biologists are yet to identify over 80% of the presumed number of species in the world. Some insects thrive in certain seasons meaning that a researcher may fail to count them if he conducts the research when they are in dormant status. In add...
There are millions of insect species in the world including some that live in places where human beings have not been able to access. Insects are small creatures that are adaptive to diverse environments. Some have a long evolutionary history coupled with high flight capability. On the other side, insects have remarkable reproductive abilities whic...
Taking the mean of most of these new estimates indicates that globally there are approximately 1.5 million, 5.5 million, and 7 million species of beetles, insects, and terrestrial arthropods, respectively. Previous estimates of 30 million species or more based on the host specificity of insects to plants now seem extremely unlikely.
Nov 30, 2022 · The IUCN Red List tracks the number of described species and updates this figure annually based on the latest work of taxonomists. In 2022, it listed 2.16 million species on the planet. In the chart, we see the breakdown across a range of taxonomic groups – 1.05 million insects, over 11,000 birds, over 11,000 reptiles, and over 6,000 mammals.

Globally, scientists have identified about 925,000 species of insects, says Hogg, the entomology professor. Estimates on the number of total insects species fall as high as 30 million and as low as 2 million. The estimate that many people agree upon is about 5 million, so biologists have yet to identify more than 80 percent of the estimated ...
Estimates of the total number of insect species vary considerably, suggesting that there are perhaps some 5.5 million insect species in existence, of which about one million have been described and named. These constitute around half of all eukaryote species, including animals, plants, and fungi.
Nov 20, 2023 · Overall, they projected that there are 8.75 million living species, of which only 1.2 million were described (including approximately 0.95 million animal species). Mora and colleagues validated this approach by comparing their projections [ 4] to those from expert opinion [ 5 ].
