<P> The waggle dance may be less efficient than once thought . Some bees observe over 50 waggle runs without successfully foraging, while others will forage successfully after observing 5 runs . Likewise, studies have found that honeybees rarely make use of the information communicated in the waggle dance and seem to only do so about ten percent of the time . Evidently there is a conflict between private information, or individual experience, and social information transmitted through dance communication . 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 . </P> <P> The waggle dance may be adaptive 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 become obsolete quickly . As a result, foragers 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 can still successfully forage when the dance is experimentally obscured . In tropical habitats, honey bee foraging is severely impaired if waggle dancing is prevented . This 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 . </P> <P> Ancestors to modern honeybees most likely performed excitatory movements to encourage other nestmates to forage . These excitatory movements include shaking, zig - zagging, buzzing and crashing into nestmates . Similar behavior is observed in other Hymenoptera including stingless bees, wasps, bumblebees and ants . </P> <P> The waggle dance is thought to have evolved to aid in communicating information about a new nest site, rather than spatial information about foraging sites . </P>
