 Similarly, queenless colonies of "A. andreniformis" have been seen to join "A. florea" colonies, but in these cases, any "A. andreniformis" larva are usually destroyed by the host colony, preventing parasitism from the foreign species.Worker bees of "A. florea" have complete reproductive dominance over "A. Andreniformis" in a queenless nest because they have recognition and kin selection, while "A. Andreniformis" does not.However, when a queen is present, worker bees do not reproduce and parasitism is turned off.
