Von Frisch's dance language theory is offen disputed; there are zoologists who argue foragers' movements are intended only to attract the attention of other bees. Instead, they believe olfactory data from the initial pollen sample found by the forager is enough to transmit the source's location. Even supports of the dance language theory acknowlage the importance of smell. In fact, they feel that, although foragers' communicative dances can guide bees to vicinity of a pollen store, olfactory clues are used to pinpoint the exact source. ---
