An insect resembling a leaf Entomology (from Greek ἔντομος, entomos, "that which is cut in pieces or engraved/segmented", hence "insect"; and -λογία, -logia[1]) is the scientific study of insects, a branch of arthropodology, which in turn is a branch of zoology.
In the past the term "insect" was more vague, and historically the definition of entomology included the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, land snails, and slugs. This wider meaning may still be encountered in informal use. At some 1.3 million described species, insects account for more than two-thirds of all known organisms,[2] date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth.
