Beekeeping
The queen is the only sexually mature female in the hive and all of the female worker bees and male drones are her offspring. The queen may live for up to three years or more and may be capable of laying half a million eggs or more in her lifetime. At the peak of the breeding season, late spring to summer, a good queen may be capable of laying 3,000 eggs in one day, more than her own body weight. This would be exceptional however; a prolific queen might peak at 2,000 eggs a day, but a more average queen might lay just 1,500 eggs per day. The queen is raised from a normal worker egg, but is fed a larger amount of royal jelly than a normal worker bee, resulting in a radically different growth and metamorphosis. The queen influences the colony by the production and dissemination of a variety of pheromones or "queen substances". One of these chemicals suppresses the development of ovaries in all the female worker bees in the hive and prevents them from laying eggs.

"Lasius niger" colonies can reach in size up to around 40,000 workers in rare cases but 4,000–7,000 is around average. A "Lasius niger" queen can live up to around 15 years and it has been claimed that some have lived for 30 years. "Lasius niger" queens while in the early stages of founding can have two to three other queens in the nest. They will tolerate each other until the first workers come, then it is most likely they will fight until one queen remains. In certain circumstances, it is possible that there can be multiple queens in a single colony if they are founding somewhat near each other and eventually their two tunnels connect.. Under laboratory conditions, workers can live at least 4 years.
