Resumen de Beehives take in drifters in times of plenty
Honeybees may have a unique system for accepting migrants. "Drifting" bees that wander into a hive may stay -- if the guard bees see fit. Such drift is common in apiaries, where hives are placed close together. A bee that drifts essentially migrates from its own hive to another, probably unintentionally. Morgane Nouvian and her team at the University of Queensland in Brisbane, Australia, reviewed 161 papers on how honeybees defend their hives to get an overview of the phenomenon. They report that 10%-15% of honeybees take on nest-guarding roles, usually when 2-3 weeks old.
