Etymology: Odonata is a scientific name, coined in the 19th century from Greek. The Greek "odōn" (genitive "odontos") means "tooth," and the order was named for the strong, toothed mandibles that dragonflies and damselflies use to catch and chew their prey in mid-air. Entomologists formed the Latinized name "Odonata" from that root, the same root that gives English "odontology," the study of teeth. The order was named in 1819 (sometimes attributed to Fabricius-era taxonomy, but the modern form traces to the early 19th century), so the word has no ancient history: no classical writer ever used it. The insects themselves were familiar to people long before, but the name is a deliberate piece of scientific classification built on a Greek word for a body part.
