When the queen through some accident or other has perished, the plebeian population of the hive very quickly perceive the misfortune, and without losing time in useless regrets, apply themselves to repair their loss. They choose the larva of a working bee, less than three days old, on which they bestow the treatment suited to change it into a female. The workers enlarge the cell of this grub by demolishing the surrounding cells, and administer to it a strong dose of royal food, to effect its transformation. This marvellous metamorphosis is accomplished like those which one reads of in fairy tales, where so many poor beggars are changed, by a wave of the hand, into beautiful princesses, covered with gold and precious stones. Only here the fairy tale is a true story; the poet's dream is a real phenomenon. According to Francis Huber, the larva intended to produce a female has to change its position. The workers add then to its domicile a sort of vertical tube, into which they push and turn round the young grub which is the hope of the community. For twelve days a bee, a sort of body-guard, has special charge of the person of our infant. It offers it food, and pays it many other delicate little attentions. When the moment for the metamorphosis has come, the orifice of the tube is closed, and the bees await the hatching of the new queen. Thus the loss of the queen is speedily replaced. The larvæ of the queens, when they are shut up in their cells, have the head downwards, whilst the larvæ of the males have the head upwards. Their hatching takes place thirteen days after the laying of the eggs. As soon as they have quitted their cradles, the young queens are ready to take flight. The others, workers and males, are less strongly organised. Before they are able to take a part in the sports and labours of the old ones they require a rest of twenty-four hours, during which the nurses lick them, brush them, and offer them honey. But the young workers require to undergo no apprenticeship before they do the work which devolves upon them. They go straight to their work, and suppress all apprenticeship. Nature is their guide and counsellor.
