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]
The largest is the dobsonfly Acanthacorydalis fruhstorferi, which can have a wingspan of up to 21.6 cm (8.5 in), making it the largest aquatic insect in the world by this measurement. [38] This species is native to China and Vietnam, and its body can be up to 10.5 cm (4.1 in) long. [39]
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]
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
There has also been a history of people becoming entomologists through museum curation and research assistance, [11] such as Sophie Lutterlough at the Smithsonian National Museum of Natural History. Insect identification is an increasingly common hobby, with butterflies [12] and (to a lesser extent) dragonflies being the most popular. [13]
