There are two theories concerning the origin of the female andw^orker bees. One very doubtful one is as follows ; and the othercan be best understood by referring to Von Siebolds researcheson Polistcs gallica, already mentioned. The bees produce fertile or sterile females (workers), accord-ing to their w^ill, and probably the feeding of the larvae has muchto do with the development into egg-bearing or sterile and then it happens that the larvae of workers (sterile bees),which are located in cells near that of a fertile female larva (afuture queen) receive, more or less accidentally, some of theparticular nourishment intended for their important small quantity of royal food alters the condition of the de-velopment of the reproductive organs in the workers, and theybecome more or less able to lay. When a hive has lost its. THE 261 queen the bees produce others by feeding up the larvae whichshould be workers. A larva is chosen for this important position, and its cell isenlarged, the neighbouring insects and their cells being destroyedto make room. Then the larva is fed up royally, and the develop-ment of its reproductive system increases, so that finally a changeinto a fertile female is perfected. It is perfectly certain that a maiden female can producea progeny, and that when there are several fertile females asso-ciated with males they fight until one is the conqueror, theworkers dragging out the dead, and witnessing the combat.
