European Honey Bee
European worker bees secrete the wax used to build the hive, clean, maintain and guard it, raise the young and forage for nectar and pollen, and the nature of the worker’s role varies with age. For the first ten days of their lives, worker bees clean the hive and feed the larvae. After this, they begin building comb cells. On days 16 through 20, workers receive nectar and pollen from older workers and store it. After the 20th day, a worker leaves the hive and spends the remainder of its life as a forager. Although worker bees are usually infertile females, when some subspecies are stressed they may lay fertile eggs. Since workers are not fully sexually developed, they do not mate with drones and thus can only produce haploid (male) offspring.
