Sensitivity encourages return to hive before storm: bees
 

Bees protect themselves from approaching storms by sensing electromagnetic waves.

       
  "Bees, for instance, are very responsive to electrical discharges in the air that occur just before a thunderstorm, ultimately causing lightning, which in turn generates electromagnetic waves. These waves stimulate bees to return swiftly to their hives and remain inside until the storm is over." (Shuker 2001:64)
