Metamorphosis of Waxthey are of the same general outline as are the cuticular surfaces of the wax mirrors on which they form (Fig. 3.1), those of the last pair of wax mirrors being somewhat smaller than the more uniform anterior mirror pairs (Huber 1814; Dreyling 1903). The wax scales vary in thickness depending upon t

Unfortunately, this old truth hides a horrible conundrum in which the role of brood as a stimulus for wax production lies hidden among many other complex and interd

The Queen possibility that the queen bears a specific relationship to the synthesis and secretion of wax as well as to comb-building is a more recent idea. Indeed, De Reaumur (1740) was the first to note that a caged colony of queenless bees had constructed comb after 2 days’ confinement. However, he had giv
