Coordinated wing-waving in bees

Why Evolution Is True

The tweet at the bottom got me looking for longer videos of this mesmerizing behavior, and I found one (from BBC Earth) on YouTube. The coordinated wing displays are said to deter predators, and I can’t think of any other reason for it, but I wondered if it there really were data showing that it has this effect.  This PLOS One paper, however, shows that the shimmering effect of coordinated wing-waving really does deter wasps from picking honeybees out of the mass on the nest.

Another problem is how the bees manage to synchronize their movements so rapidly. In birds like starlings, which also move and change direction rapidly in similar “waves” during their murmutations, it’s been shown that this movement requires each bird to pay attention to and emulate the movements of six or seven neighboring birds.
