    Globally, averages of these predictions estimate there are around 1.5 million beetle species and 5.5 million insect species, with around 1 million insect species currently found and described. [3] 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 ...

    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]

    In 2011 a study published in PLoS Biology estimated there to be 8.7 million ± 1.3 million eukaryotic species on Earth. [11] By 2017, most estimates projected there to be around 11 million species or fewer on Earth. [4] A 2017 study estimated there are around at least 1 to 6 billion species, 70-90% of which are bacteria. [4]

    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 ]

    [147] [150] Several groups of insects can be considered as either micropredators or external parasites; [151] [152] for example, many hemipteran bugs have piercing and sucking mouthparts, adapted for feeding on plant sap, [153] [154] while species in groups such as fleas, lice, and mosquitoes are hematophagous, feeding on the blood of animals.

  7. List of herbivorous animals - Wikipedia

    Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
