Scott Carroll and Jenella Loye carefully analyzed the interactions of soapberry bug populations and their plant hosts worldwide. They discovered that populations of soapberry bugs living on weedy, non-native plants rapidly because less adapted to their native food source. All of this occurred while the bugs simultaneously experienced a multitrait evolution to capitalize on the introduced plants.
As host plants invade new environments worldwide, native soapberry bugs are colonizing them and converging onto similar adaptive forms.
