Works
Fabricius is considered one of the greatest entomologists of the 18th century. He was a greater observer of insects than his more botanically-minded mentor, Carl Linnaeus. Fabricius named 9,776 species of insects, compared to Linnaeus' tally of around 3,000.
In contrast to Linnaeus' classification of the insects, which was based primarily on the number of wings, and their form, Fabricius used the form of the mouthparts to discriminate the orders (which he termed "classes"). He stated "those whose nourishment and biology are the same, must then belong to the same genus". Fabricius' system remains the basis of insect classification today, although the names he proposed are not. For instance, his name for the class containing the beetles was "Eleutherata", rather than the modern "Coleoptera", and he used "Piezata" for Hymenoptera; his term Glossata is still in use, but for a slightly smaller group almong the Lepidoptera, rather than the whole order. Fabricius also foresaw that the male genitalia would provide useful characters for systematics, but could not apply that insight himself.
Fabricius was the first to divide the Staphylinidae (rove beetles), which Linnaeus had considered a single genus he called "Staphylinus," establishing in 1775 the genus Paederus. He also described 77 species of Staphylinidae.
His major works on systematic entomology were:
- Systema entomologiæ (1775)
- Genera insectorum (1776)
- Species insectorum (1781)
- Mantissa insectorum (1787)
- Entomologia systematica emendata et aucta (1792–1799)
- Systema eleuthatorum (1801)
- Systema rhyngotorum (1803)
- Systema piezatorum (1804)
- Systema antliatorum (1805)
- Systema glossatorum (1807)
Fabricius' collections are shared between the Natural History Museum, London, the Muséum national d'histoire naturelle, Paris, the Hope Department of Entomology, Oxford, the Hunterian Museum and Art Gallery, Glasgow, the Zoological Museum in Kiel, Kiel, and the Statens Naturhistoriske Museum, Copenhagen.
Fabricius also wrote a few works on economics, although these are much less important than his zoological works. They include Begyndelsesgrundene i de økonomiske Videnskaber (1773), Polizeischriften (1786–1790) and Von der Volksvermehrung, insonderheit in Dänemark (1781).

Famous quotes containing the word works:
“The discovery of Pennsylvania’s coal and iron was the deathblow to Allaire. The works were moved to Pennsylvania so hurriedly that for years pianos and the larger pieces of furniture stood in the deserted houses.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
“I look on trade and every mechanical craft as education also. But let me discriminate what is precious herein. There is in each of these works an act of invention, an intellectual step, or short series of steps taken; that act or step is the spiritual act; all the rest is mere repetition of the same a thousand times.”
—Ralph Waldo Emerson (1803–1882)
“My plan of instruction is extremely simple and limited. They learn, on week-days, such coarse works as may fit them for servants. I allow of no writing for the poor. My object is not to make fanatics, but to train up the lower classes in habits of industry and piety.”
—Hannah More (1745–1833)
