W. P. Pycraft,
The Courtship of Animals
“ The cells destined to produce the workers are the smallest, those for drones are larger, and those for queens are largest of all, and the walls are formed of pure pollen, not of wax as are those of the workers and drones. But it would seem that she never lays an egg in any of the last named. The sight of a queen-cell rouses her to fury. These cells, then, are filled by the workers, who remove the requisite number of worker—eggs from the cells in which they were laid and deposit them in the queen-cradles. ”
