Mason Bee

a small wild bee. It constructs a solitary nest of sand or gravel fastened together with a sticky saliva manufactured by the bee. The nest is placed in the sheltering angle of a wall, under a stone, or even in a place hollowed out in the pith of a leaf or twig. The queen bee usually constructs a number of cells in the same fastness, each of which contains a single egg and a store of honey for the young larva to feed upon. See Bee; Wasp
