Between 950,000–1,000,000 of all described animal species are considered insects, so over 50% of all described eukaryotes (1.8 million species) are insects (see illustration). With only 950,000 known non-insects, if the actual total number of insects is 5.5 million, they may represent over 80% of the total, and with only about 20,000 new ...
Recent figures indicate that there are more than 1.4 billion insects for each human on the planet, [27] or roughly 10 19 (10 quintillion) individual living insects on the earth at any given time. [28] An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. [28]
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of July 2016, the International Union for Conservation of Nature (IUCN) listed 195 critically endangered insect species, including 46 which are tagged as possibly extinct. [1] [2] Of all evaluated insect species, 3.2% are listed as critically endangered ...
Many species have been recorded as breeding in natural materials or refuse such as owl pellets, bat caves, honey-combs or diseased fruit. [ 5 ] Of the approximately 174,250 lepidopteran species described until 2007, butterflies and skippers are estimated to comprise approximately 17,950, with moths making up the rest.
Additionally 1702 insect species (28% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
In contrast, a large majority of the insect species of the tropics and the southern hemisphere are probably undescribed. [11] Some 30–40,000 species inhabit freshwater; very few insects, perhaps a hundred species, are marine. [12] Insects such as snow scorpionflies flourish in cold habitats including the Arctic and at high altitude. [13]
