'''Entomology''', from the [[Ancient Greek|Greek]]: ''entomo-''/εντομο- "that which is cut in pieces or engraved/segmented", hence "insect"; and ''logos''/λόγος, "knowledge",<ref name="Liddell 1980">{{cite book | author = [[Henry George Liddell|Liddell, Henry George]] and [[Robert Scott (philologist)|Robert Scott]] | year = 1980 | title = [[A Greek-English Lexicon]] (Abridged Edition) | publisher = [[Oxford University Press]] | location = United Kingdom | id = ISBN 0-19-910207-4}}</ref> is the [[science|scientific]] study of [[insect]]s. At some 1.3 million described species, insects account for more than 2/3rds of all known organisms,<ref name="Chapman">{{cite book |author=Chapman, A. D. |year=2006 |title=Numbers of living species in Australia and the World |pages=60pp |Publisher=Canberra: [[Australian Biological Resources Study]] |id=ISBN 978-0-642-56850-2 |url=http://www.deh.gov.au/biodiversity/abrs/publications/other/species-numbers/index.html}}</ref>dating back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth, so it is an important specialty within [[biology]]. Though technically incorrect, the definition is sometimes widened to include the study of terrestrial [[animals]] in other [[arthropod]] groups or other [[phylum|phyla]], such as [[arachnid]]s, [[myriapod]]s, [[earthworm]]s, and [[slug]]s.

Like several of the other fields that are categorized within [[zoology]], entomology is a [[taxon]]-based category; any form of scientific study in which the organisms studied happen to be insects is, by definition, entomology. Entomology therefore includes a cross-section of topics as diverse as [[molecular genetics]], [[behavior]], [[biomechanics]], [[biochemistry]], [[systematics]], [[physiology]], [[developmental biology]], [[ecology]], [[morphology (biology)|morphology]], [[paleontology]], [[anthropology]], [[robotics]], [[agriculture]], [[nutrition]], and more.

==History of entomology==
{{main|Timeline of entomology}}

Entomology is rooted in nearly all human [[culture]]s from [[prehistoric]] times, primarily in the context of [[agriculture]] (esp. [[biological control]] and [[beekeeping]]), but [[scientific]] study began only as recently as the 16th century <ref>Antonio Saltini, ''Storia delle scienze agrarie'', 4 vols, Bologna 1984-89, ISBN 88-206-2412-5, ISBN 88-206-2413-3, ISBN 88-206-2414-1, ISBN 88-206-2414-X</ref>
. The [[list of entomologists]] through recorded history is enormous, and includes such notable figures as [[Charles Darwin]], [[Vladimir Nabokov]], [[Karl von Frisch]] (winner of the 1973 [[Nobel Prize in Physiology or Medicine]]), and two-time [[Pulitzer Prize]] winner, [[E. O. Wilson]]. Entomology has even entered popular modern culture; [[Gil Grissom]] on the [[CSI: Crime Scene Investigation]] TV show is an entomologist, who is played by actor [[William Petersen]].

==Identification of insects==
Insects other than [[Lepidoptera]] are typically identifiable only through the use of [[Identification key]]s and [[Monograph]]s. Because the class [[Insecta]] contains a very large number of species and the characters separating them are unfamiliar, and often subtle (or invisible without a [[microscope]]), this is often very difficult even for a specialist.

Insect identification is an increasingly common hobby, with [[butterfly|butterflies]] and [[dragonfly|dragonflies]] being the most popular.

==Taxonomic specialization==
[[Image:Beetle collection.jpg|thumb|250px|right|Part of a large [[beetle]] collection]]
Many entomologists specialize in a single order or even a family of insects, and a number of these subspecialties are given their own informal names, typically (but not always) derived from the scientific name of the group:
*[[Apiology]] (or [[melittology]]) - [[bee]]s
*[[Coleopterology]] - [[beetle]]s
*[[Dipterology]] - [[flies]]
*[[Hemiptera|Hemipterology]] - [[Hemiptera|true bug]]s
*[[Lepidoptera|Lepidopterology]] - [[moth]]s and [[butterfly|butterflies]]
*[[Myrmecology]] - [[ant]]s
*[[Orthopterology]] - [[grasshopper]]s, [[cricket (insect)|cricket]]s, etc.
*[[Trichoptera|Trichopterology]] - [[caddis flies]]

==Organizations==
Like other scientific specialties, entomologists have a number of local, national, and international organizations. There are also many organizations specializing in specific subareas.
