Study Notes
Fossils and Amber
- Insects and their relatives predate dinosaurs, showcasing a rich evolutionary history.
- Trilobites existed between 400-600 million years ago; horseshoe crabs appeared around 350 million years ago.
- The earliest insect fossils, small and wingless, date back to approximately 380 million years ago; relatives resembling modern dragonflies emerged between 250-280 million years ago.
- Many modern insect relatives were present before the Jurassic period, around 180 million years ago.
- Mid Tertiary period saw the emergence of many contemporary insect species, around 25-30 million years ago.
Tracing the Literature
- Ancient records include cave drawings from 6,000 BC, early references to silkworms in China (~4,700 BC), honeybees and scarabs in Egypt (~3,500 BC), and body pests in Greece (~1,000 BC).
- Aristotle (384-322 BC), the Father of Zoology, authored "Historia Animalium," laying foundational observations of animals, including insects.
- Theophrastus (380-287 BC) is recognized for being the first to catalog crop pests related to insects.
- Pliny the Elder (23-79 AD) contributed extensively in "Historia Naturales," particularly in Book 11, highlighting early entomological knowledge.
- Documented species were limited, with Aristotle recognizing 47 insect species and Pliny identifying 61, including grasshoppers, beetles, bees, butterflies, flies, and aphids.
Contributions of Naturalists
- Johann Sperling (1661) documented over 40 beetle, 50 caterpillar, 70 fly, and over 100 butterfly species, emphasizing the diversity of insects.
- John Ray (1627-1705) estimated at least 150 species of butterflies and beetles in England, hypothesizing a total of around 10,000 species globally in terrestrial and aquatic environments.
Carl von Linne (Linnaeus)
- Introduced binomial nomenclature in the 10th edition of "Systema Naturae" (1758), standardizing the scientific naming of organisms and providing a systematic framework for classifying insects.
