52                  THE MIRACLE OF THE HONEYBEE


                                          in its stomach to meet its own energy needs,
                                           then flies off again at once to the food
                                            source. Any bee to which the nectar has
                                            been transferred either gives it to still
                                            other bees or else stores it away, depend-
                                            ing on the food needs of the hive on the
                                         day in question. 35


                                        Other Duties
                                        After having become adults and beginning to
                                       forage, bees can undertake all jobs. Their three-
         Mandible                       week life span is sufficient for this.
                                            We have already mentioned that changes
                              Maxilla    take place in the bee’s body throughout her
                             Labium       development, and how jobs in the hive
              Proboscis       Flabellum   change in direct proportion to bodily
                                                 changes that take place at different
                                                 times in the bee’s body. But these
                                                 changes are not irreversible. A bee’s
                                                 organs can regain their previous
                                                 functions if the needs of the hive re-
                                                 quire it. For example, when the hive



                                                  The worker proboscis can very in
                                                  length from 5.3 to 7.2 millimeters
                                                  (0.2087 to 0.2835 inches), depending
                                                  on the race. The nectar of some flow-
                                                  ers lies deeper down than in others.
                                                  It’s thus a major advantage for bees
                                                  to possess a long proboscis ideally
                                                  suited to extracting nectar from the
                                                  base of such flowers.
                                                  The pictures at top left show the
                                                  bee’s proboscis in extended and
                                                  folded positions. As can be seen
                                                  below, bees fold their proboscis in-
                                                  wards in a Z-shaped pattern when
                                                  not in use.
