Entomology

Entomology (from Greek, entomos, "that which is cut in pieces or engraved/segmented", hence "insect"; and -logia) is the scientific study of insects, 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.

Quotes
"Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name. No man can be truly called an entomologist, sir; the subject is too vast for any single human intelligence to grasp."
 * "I suppose you are an entomologist"
 * Oliver Wendell Holmes, The Poet at the Breakfast Table.
