In addition to the pheromones, bees use tactile and sound interactions to communicate. The waggle dance is usually used to indicate a food source. In this dance, the bee waggles through a stretch of the comb and returns to the beginning of this stretch in a semicircle path. After that, it waggles again the same stretch and returns in a new semicircle path to the beginning, this time using the opposite side. By analyzing the layout of the path, the time spent in the dance, the route and the number of executions, the bees will know the quality, distance and direction where the food source is.
