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.
- James Petiver publishes a celebrated butterfly work Lepidoptera of the Philippine Islands.
- The world’s oldest pinned insect specimen; a Bath White butterfly preserved in Oxford University Museum.
- 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.

Until the publication of this encyclopedia it was thought that all animals were created together by God about 6,000 years ago. 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.
- Maria Theresa of Austria instructs Gerhard van Swieten to establish Vienna as an important centre of natural science. Many entomologists train there.

- 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.

1800 – an arbitrary date but it was around this time that systematists began to specialise. There remained entomological polyhistors – those who continued to work on the insect fauna as a whole.
From the beginning of the century, however, the specialist began to predominate, harbingered by Johann Wilhelm Meigen‘s Nouvelle classification des mouches à deux aile (New classification of the Diptera) commenced in the first year of the century. Lepidopterists were amongst the first to follow Meigen’s lead. The specialists fell into three categories. First there were species describers, then specialists in species recognition and then specialists in gross taxonomy. There were however considerable degrees of overlap. Also then, as now, few could entirely resist the lure of groups other than their own, and this was especially true of those in small countries where they were the sole ‘expert’, and many famous specialists in one order also worked on others. Hence, for instance, many works which began as butterfly faunas were completed as general regional works, often collaboratively.

- A paper in Science found that Culex pipiens mosquitoes existed in two populations in Europe, one which bites birds and one which bites humans. In North America 40% of Culex pipiens were found to be hybrids of the two types which bite both birds and humans, providing a vector for West Nile virus. This is thought to provide an explanation of why the West Nile disease has spread more quickly in North America than Europe.
