every solitary
   

   bee species
      

      has its own
   

   peculiarities



but their habits


   as a whole


      are typically


   monotonous



nesting


   in the ground


      in cavities


   crevices



or earthen cells


   lined with
      leaves


   or petals



provisioned


   with balls


      of honeyed


   pollen*


the honeybees

   society
      is achieved by
   repeating

various motifs
   of the wasp
      set in a different
   key

* commonly called bee-bread
