laying worker bee
A laying worker bee is a worker bee that lays unfertilized eggs usually in the absence of a queen bee. Only drones develop from the eggs of laying worker bees (with some exceptions, see thelytoky). A beehive cannot survive with only a laying worker bee.〔(Michael Bush ). Laying workers. Bushfarms.com〕
==Prevalence==
Even in a normal hive, about 1% of workers have ovaries developed enough to lay eggs. However the usual number of the laid eggs is very small. Only eight eggs (seven moderately and one fully developed) were found after examining of 10,634 worker bees〔Thomas D. Seeley (1996). The Wisdom of the Hive〕 (strong colony contains about 100,000). Workers eventually lay significant numbers of eggs only in queenless colonies.
