Abstract - In 3 consecutive years (1990-1992) drones of Apis cerana japonica were observed pursuing queen dummies in a comet-shaped swarm above prominent trees (Zelkova serrata) at a shrine in Morioka, northern Japan. The height of the Zelkova tree was between 17.2 and 22.5 m. Thus, drones of A c japonica aggregate at landmark mating areas like tree tops. Drones were marked at their colonies and some were recaptured at the drone congregation area at a distance of 500 m from their colonies.
Key words: Apis cerana japonica / drone congregation area / tree topping / Zelkova serrata / reproductive behavior
