 In mutualistic relationships, the production of honeydew by trophobionts is rewarded by removal of dead hemipterans and protection from a variety of predators by the attendant ants.In some relationships the ants will build shelters for the farmed trophobionts, either to protect them or keep them from leaving the area.Some species of ants construct underground rooms to house the trophobionts and carry them between the host plant and housing area daily.
