      CCD has nothing to do with starvation of colonies. In other words, if
      you have a colony of dead bees inside your hive, you haven't
      experienced CCD.

      Colony Collapse Disorder (or CCD) is a poorly understood phenomenon in
      which worker bees in a beehive or Western honey bee colony abruptly

      CCD was originally found only in Western honey bee colonies in North
      America. European beekeepers were reported to have observed a similar
      phenomenon in Poland, Greece, Italy, Portugal, and Spain, and initial
      reports have also come in from Switzerland and Germany, albeit to a
      lesser degree. None of the supposed cases outside the US has been
      confirmed, as of June, 2007, to show the telltale signs of CCD.

      The cause (or causes) of the syndrome is not yet well understood: even
      the existence of this disorder remains disputed. Theories include
      environmental change-related stresses, malnutrition, unknown pathogens
      (i.e., disease), mites, pesticides such as neonicotinoids, emissions
      from cellular phones or other manmade devices, and genetically
      modified (GM) crops. That the disappearances have only been reported
      from a subset of the commercial beekeepers in affected areas (i.e.,
      not feral colonies or organic beekeepers), suggests to some that
      beekeeping practices can be a primary factor.

      From 1971 to 2006 approximately half of the U.S. honey bee colonies
      have vanished, but this decline includes the cumulative losses from
      all factors such as urbanization, pesticide use, tracheal and Varroa
      mites and commercial beekeepers retiring and going out of business,
      and has been somewhat gradual. Late in the year 2006 and in early
      2007, however, the rate of attrition was alleged to have reached new
      proportions, and the term "Colony Collapse Disorder" was proposed to
      describe this sudden rash of disappearances.

      Limited occurrences resembling CCD have been documented as early as
      1896, and this set of symptoms has in the past several decades been
      given many different names (disappearing disease, spring dwindle, May
      disease, autumn collapse, and fall dwindle disease). Most recently, a
      similar phenomenon in the winter of 2004/2005 occurred, and was
      attributed to Varroa mites (the "Vampire Mite" scare), though this was
      never ultimately confirmed. In none of the past appearances of this
      syndrome has anyone been able to determine its cause(s). Upon
      recognition that the syndrome does not seem to be
      seasonally-restricted, and that it may not be a "disease" in the
      standard sense—that there may not be a specific causative agent—the
      syndrome was renamed.
