They select, when not more than three days old, an egg previously intended for a worker bee--but a larva will serve, so it be not grown to its full size--and then they enlarge the cell so selected by destroying the surrounding partitions; they thus form a royal cradle, in shape very much like an acorn-cup inverted. The chosen embryo is then fed liberally with a peculiar description of nurture, called by naturalists "royal jelly"--a pungent food composed of honey and digested pollen, and prepared by the worker bees exclusively for those of the larvæ that are destined to become candidates for the honour of royalty. The effect of this is both to perfect and to hasten the development of the future insect, so that instead of a worker being produced at the end of twenty-one days, a queen emerges in the reduced term of sixteen. But should the deprivation happen at a time when, either from the season or from abnormal circumstances, there is no worker brood in the hive, the bees will then often exhibit a series of curious and even ludicrous struggles, which Von Berlepsch has aptly compared to the clutchings at straws made by a drowning man. Themselves individually are no sufferers; but bees look beyond themselves, and posterity they must have. Their sole preoccupation, therefore, is to raise drones and a queen. Some of them often develop a capacity to lay drone eggs (as explained under § ix.), and most of these they will carefully cherish for their natural purpose, but others they will surround with royal cells and feed with royal jelly, so that the poor things on hatching are soon dosed to death in a frantic effort to change their sex! And if drone eggs are not to hand they will even try to hatch a queen out of a lump of pollen! In more senses than one then we see that when bees have lost their queen they have lost their head. As curiously dissimilar, though not discordant, instances of the effect of removing the queen from a hive, we may mention that Mr. Langstroth once tried the experiment for only two or three minutes, when he had all in confusion immediately, and found two days after that royal cells had been prepared; while Dr. Bevan once effected the removal so quietly that for eighteen hours all went on as usual, and then on a sudden the fact became known, and everything was changed into agitation and distraction. Should a queen so separated be detained from her subjects, she resents the interference, refuses food, pines, and dies.
