Explanation

a) Drones are robust, large winged small numbered, short lived and fed with bee bread by nurse workers. They are developed from unfertilized ova by arrhenotoky (male parthenogenesis).
b) Worker bees are multifaceted sterile females which develop from the fertilised eggs and perform diverse functions. They live for two or three months. They are very small in size.
