Honeybee queens have sex with harems of males apparently to give birth to much better dancers, research reveals. North American honeybee queens each have sex with an average of seven to 20 males, with the giant honeybee in Asia know to demand up to 104 mates
To see why honeybee queens might prefer a life of promiscuity, researchers compared a trio of queens each inseminated by just one male drone with a trio of queens inseminated by 15 drones.
The genetically diverse colonies of queens inseminated by 15 males turned out better dancers — they performed more waggle dances and longer dances. Worker bees use waggle dances to reveal where food is to nest mates, and genetically diverse colonies dispatched more foragers to look for food.
"What really surprised us was the extent of difference," researcher Heather Mattila, a honeybee behaviorist at Cornell University in Ithaca, N.Y., told LiveScience. "In some colonies, you can see the less genetically diverse bees pretty much just standing still on the honeycombs on the videotape, while bees in the genetically diverse colonies are dancing or have left to go forage."
