Fanning honeybee exposes Nasonov gland (white-at tip of abdomen) releasing pheromone to entice swarm into an empty hive

Nasanov pheromone is released by worker bees to orient returning forager bees back to the colony. To broadcast this scent, bees raise their abdomens, which contain the Nasonov glands, and fan their wings vigorously.

Nasonov includes a number of different terpenoids including geraniol, nerolic acid, citral and geranic acid. Bees use these to find the entrance to their colony or hive, and they release them on flowers so other bees know which flowers have nectar. The terpenoids, sometimes referred to as isoprenoids, are a class of naturally occurring chemicals similar to terpenes, derived from five-carbon isoprene units assembled and modified in thousands of ways. ...
