This short phone clip shows the honeybee Nasanov gland on full display.

These bees were signaling to their sisters that the colony has occupied a swarm trap and all flying bees should come to the scent.

Forgive the shakiness of the handheld video shot but at some points in the video, you can really see the anatomy of the bee's scent gland at the tip of the abdomen. Kind of reminds one of how the Concorde jet nose used to work if you are old enough to know the reference.
