Insect population decline affects ecosystems, and other animal populations, including humans. Insects are at "the structural and functional base of many of the world's ecosystems." [6] A 2019 global review warned that, if not mitigated by decisive action, the decline would have a catastrophic impact on the planet's ecosystems. [6]
For 203 insect species that had IUCN-documented population trends in 2013, 33% were in decline with variation in documented species across orders. [13] Most scientific and public attention has been focused on the conservation of larger, charismatic vertebrates, and relatively fewer studies have been done on insect groups, especially Diptera ...
An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. [28] Ants have colonised almost every landmass on Earth. Their population is estimated as between 10 16 –10 17 (10-100 quadrillion). [29]
To say that ants outnumber people on Earth would be a gross understatement. Earth's ant population of 20 quadrillion outnumbers humans by 2.5 million times, study finds Skip to main content
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...

The inverse relationship of size and population recurs higher on the evolutionary ladder—to a first approximation, all multicellular species on Earth are insects". [189] Insect extinction rates are high—supporting the Holocene extinction hypothesis. [190] [58]
There isn’t much data available to the wider public on the Calathus lundbladi ground beetle. This elusiveness is in no small part due to the little bug’s position on the International Union ...
