Newly emerged virgin honey bee queens become inseminated in flight by multiple male honey bees (drones) in elevated regions called Drone Congregation Areas (DCAs). These DCAs are areas five to 60 meters above ground and 30 to 200 meters in diameter. They can persist in the same place for dozens of years – longer than the life of any queen (a couple years) and much longer than the life of a drone (21-32 days!). This raises a question: How do queens and drones know where the DCA is year after year. Since drones and queens arrive at DCAs from multiple colonies, it is believed that DCAs exist so that queens can maximize the genetic diversity in their colony. Somehow, they all know where to go to link up. To try …
