Because worker relatedness is so high in "D. maculata", workers are more related to other workers' sons than to the queen's own sons, and therefore worker policing of egg production does not occur. An explanation for the queen's near monopoly on male production is that worker production is costly and therefore reduces total colony reproduction. The cost toward worker production
