Abstract: A netting material comprises a main portion and a netted window portion. The main portion has apertures of a first aperture size and shape, and the netted window portion has apertures of a second aperture size and shape. The apertures of the netted window portion are of sufficient size and shape to allow honey bees to pass through the netting material, whereas the apertures of the main portion are of sufficient size and shape to substantially prevent honey bees passing through the netting material.
