They go so far as to become the primary pollen and nectar providers for the colony. Male bees are short-lived; their only task is to mate with new queens as they emerge. The queen is the largest; she may be up to ¾ inch long while workers and males are usually about ½ inch. , The overwintering queen first appears during spring and establishes underground colonies.
