For nearly 2000 years the few writers who dealt with zoological subjects followed Aristotle's leading.

The development of entomology in the 18th century
In the 18th century three kinds of entomological text appeared. Firstly there were illustrative works – showy insects often beautifully coloured whose purpose was sensual. An example is afforded by Maria von Merian's Metamorphosis Insectorum Surinamenis (1705).
Secondly were descriptive and systematic (classificatory) works usually confined to what are now known as the Insecta. Of the second kind Carl von Linne's Systema Naturae published in 1758 at Uppsala stands proud. In this work the binomial system was finally settled on.
Thirdly were works on developmental biology (life cycles), internal anatomy, physiology and so on. These often covered other invertebrate groups. An example is René Antoine Ferchault de Réaumur's Memoires pour Servir a L’Historie des Insectes.
- Prussian Academy of Sciences founded in Berlin.

- Maria Sybilla Merian Metamorphosis Insectorum Surinamenis (Transformations of the insects of Surinam) published by G. Valck in Amsterdam. It is a masterpiece of both art and science and Maria Merian, "the mother of entomology", was the first to record the full life cycle of many species of butterflies and moths.
- John Ray publishes Methodus Insectorum.

- Microscopist Jan Swammerdam's Biblia naturae or "Book of Nature" is reissued. Describing his studies of insects, it is a founding work of entomology. It is in Latin Swammerdam's co-authors were Herman Boerhaave and Hieronymus David Gaubius.

Not only did this 44 volume encyclopedia contain all biological knowledge of its time, it offered a different theory. 100 years before Darwin, Buffon claimed that man and ape might have a common ancestor. His work also had significant impact on ecology.

- Tenth edition of Carl Linnaeus' Systema Naturae published. World explorers brought back to Europe so many exotic plant and animal specimens that chaos loomed for the 18th-century naturalists attempting to identify, classify, and communicate what they had gathered. Linnaeus made a great contribution to science by developing systems of classification to organize these processes. His principles of organization, especially his system of binomial nomenclature, provided essential tools for entomology. The tenth edition (1758–59), was chosen as the starting point for zoological nomenclature.

Unlike his Swedish contemporary Carl Friedrich Fallen he based higher categories on a combination of characters not following Fabricius in using mouthpart characters alone. This new approach was controversial.
