Document Summary
The class insecta has subclasses, the holometabola and the hemimetabola. Honey bees are holometabolous insects because they pass through complete metamorphosis (transformation). The first three stages are known as brood. Egg: 3 days for the three castes. Larva: 5. 5, 6 and 6. 5 days for queen, worker and drone, respectively. Pupa: 7, 12 and 14. 5 days for queen, worker and drone, respectively. The egg contains an embryo and nutrients for its development. During the larval stage, individuals pass through five instars (sub- stages), moulting (changing cuticle) while growing between instars (growth by step-wise increments). Nurse bees feed all larvae a rich food (mainly royal jelly) during their first three days after hatching. Then, they continue feeding royal jelly to those larvae that will become queens, and a mixture of pollen and nectar (bee bread) to those that will become workers or drones. During the pupal stage, the honey bee larvae develop and change into adults (metamorphosis).
