honeybees rarely make use of the information communicated in the waggle dance and seem to only do so about ten percent of the time. There can be a conflict between private information based upon individual experiences, and social information transmitted through dance communication. Essentially, foragers often prefer to use remembered information about previously rewarding food sites that they have visited and will use this information even when receiving dance information about new food sources. This sheds light on the fact that following social information is more energetically costly than foraging independently and is not always advantageous. Using olfactory cues and memory of plentiful foraging sites, honeybees are able to successfully forage independently without expending the potentially extensive energy it takes to process and execute the directions communicated by their fellow foragers. However, foragers following waggle dances will eventually switch to using public information, the food location information provided by the waggle dancer when their private information is no longer useful. The waggle dance is beneficial in some environments and not in others, which provides a plausible explanation as to why the information provided by waggle dances are only used sparingly. Depending on weather, other competitors, and food source characteristics, transmitted information may quickly degrade and become obsolete. As a result, foragers have been reported to be attached to their food sites and continue to revisit a single patch many times after it has become unprofitable. For example, the waggle dance plays a significantly larger role in foraging when food sources are not as abundant. In temperate habitats, for instance, honey bee colonies routinely perform the waggle dance but were still able to successfully forage when the location information provided by the dance was experimentally obscured. In tropical habitats, however, honey bee foraging is severely impaired if waggle dancing is prevented. This difference is thought to be due to the patchiness of resources in tropical environment versus the homogeneity of resources in temperate environments. In the tropics, food resources can come in the form of flowering trees which are rich in nectar but are scattered sparsely and bloom only briefly. Thus, in tropical zones information about forage location might be more valuable than in temperate zones. Evolution Ancestors to modern honeybees most likely performed excitatory movements to encourage other nest-mates to forage. These excitatory movements include shaking, zig-zagging, buzzing and crashing into nestmates. Similar behavior is observed in other Hymenoptera including
