0:00You've probably heard that bees use a complex series of movements – often

0:03called the "waggle dance" – to tell other worker bees where to find new sources of nectar…it’s

0:08a super clever and sophisticated system. Most communal insects lead their nestmates to

0:12promising food sources with pheromone trails. But bees – like Beatrice here – fly long distances to

0:18find flower patches; chemical signals would just disappear into the air. Instead, after

0:23returning to the hive, Bea shares information about a promising patch through choreography.

0:29The direction she moves describes the exact direction to the patch relative to the Sun.

0:33The time she spends waggling tells her sisters how far the patch is in that direction. And

0:38the intensity conveys how promising Bea thinks the patch is. This complicated set of movements

0:44adds up to a set of map coordinates tagged with a starred review. For bees.
