Abstract: A nursery habitat for flying pollinators has an axially-elongated tubular case and a multiplicity of elongated tubes. The case extends between a first end and a second end and defines an axially-elongated hollow tunnel, wherein at least one of the first end or the second end is provided with an opening. The tubes extending between a front end and a back end wherein at least the front end is open. The multiplicity of elongated tubes is disposed in closely-spaced packing inside the tunnel of the case with the open front ends of the tubes being accessible to flying pollinators through the opening in the case.

Abstract: A beehive includes a housing, a plurality of frames disposed in parallel with the frame and access doors which allow the frames to be inserted and withdrawn laterally. The frames are offset from the inner surfaces of the housing to minimize the contact areas therebetween, whereby the hard deposits formed thereon do not interfere with the removal of the frames. The inner surfaces include ramps which allow the frames to be inserted and withdrawn in an oblique path.
