In a honeybee hive, where each insect has a specific job to do, a small number of middle-aged workers serve as undertakers, removing dead bees and debris from the hive. These bees respond to the odor of the dead, finding the bodies among the wiggling living and carrying them sometimes 300 or more feet to drop them outside of the colony. It’s solo work done by about 1% of the bees at a time.

The undertaker bees apparently recognize dead bees by chemical odors that develop in the corpse shortly after death. The corpse is carried away from the colony in the mandibles of an undertaker bee (sometimes more than one). Such corpses disappear rapidly, probably eaten by scavenging insects such as ants.
