Bees can communicate with each other using the famous “waggle dance”. With special figure-of-eight gyrations, they can accurately tell other hive-mates about the location of nectar sources. Karl von Frisch translated the waggle dance decades ago but it’s just a small part of bee communication. As well as signals that tell their sisters where to find food, bees have a stop signal that silences dancers who are advertising dangerous locations. 

The signal is a brief vibration at a frequency of 380 Hz (roughly middle G), that lasts just 150 milliseconds. It’s not delivered very gracefully. Occasionally, the signalling bee will use a honeycomb to carry her good vibrations, but more often than not, she’ll climb on top of another bee first
