Nasonov pheromone

The Nasonov pheromone is a chemical signal released by worker honey bees to orient returning forager bees and swarming bees back to the colony. To release it, a bee raises its abdomen, exposing the Nasonov gland, and fans its wings to disperse the scent, which is made up of several terpenoid compounds including geraniol, nerolic acid, citral and geranic acid. Bees use the pheromone both to mark the entrance of their hive and to mark flowers already visited for nectar, and beekeepers have made synthetic versions of it to lure swarms into empty hives.
