How Many Species Of Insects As Of 2017. Conservative estimates suggest that this figure is 2 million but estimates extend to 30 million. Thus popular insects species for consumption fall into the following categories. From butterflies to bees nearly half of all insect species are threatened with extinction over the next few decades. Compared to 5416 species of mammals almost a million insect species have been described so far.
Compared to 5416 species of mammals almost a million insect species have been described so far. No subpopulations of insects have been evaluated by the IUCN. The research team recorded data on more than a million individual insects and spiders 2700 different species at hundreds of grassland and forest sites. Most Sierran terrestrial endemic insect species belong to the families of wasps and bees and of grasshoppers. It turns out the insect biodiversity in our. There are over a million described species of insect and an estimated 6-10 million species total.
1 million insect species named this suggests that 80 remain to be dis-covered and that a greater focus should be placed on less-studied taxa such as many families of Coleoptera Diptera and Hymenoptera and on poorly sampled parts of the world.
This leads some of the more liberal guessers to suggest a worldwide inventory of just insect species to be in the neighborhood of 30 million. Entomophagy or the practice of eating insects is a very broad term. Conservative estimates suggest that this figure is 2 million but estimates extend to 30 million. Of these 10 may be new to science 12 are endemic to Califor-nia and only 09 are endemic to the Sierra Nevada. The IUCN also lists 21 insect subspecies as endangered. Approximately 1900 insect species are eaten worldwide mainly in developing countries.
