A large black beetle found in Europe that makes a loud buzzing sound, also called a doodlebug or shard beetle.
From Old English 'dora,' related to the buzzing sound the insect makes. The name is onomatopoetic, mimicking the drone of the beetle's flight.
The dor beetle was so noticeable to ancient people that they named it after its sound—the word itself buzzes like the creature does. Medieval farmers considered them pests, but their loud flight actually signaled the arrival of warmer months.
