In this way, the bee works for the good of the hive rather than for the good of herself. If she stayed for the whole dance, she would know exactly how rich the source is, for instance. But if all bees waited for the entire dance to take place, and then only went to the richest sources, the colony would not be maximizing its use of available resources. This behavior is one of many instances of how, when it comes to honeybees, natural selection operates on the level of the colony, not the individual bee. With the waggle dance, a worker communicates the distance, direction, and quality of a nectar-rich flower patch to her fellow honeybees.
Honeybees perform two other types of dance.
The shake dance encourages these non-foragers to make their way to the waggle dance floor. Walking slowly around the nest, the dancer quivers her legs, causing her body to tremble forward and backward and from side to side. Lasting sometimes more than an hour, the tremble dance stimulates additional bees to begin processing nectar.
