The richness and diversity of native ant species on Mt. Desert Island, Maine, have been reduced in areas infested with Myrica rubra (European red ant). In general, the success of invasive ant species has been attributed to interference and exploitative competition coupled with the ants’ opportunistic diets. In field experiments on Mount Desert Island, Maine, M. rubra discovered and recruited to baits faster than native ants. This study also showed that M. rubra displaced most native ant species from food resources (Garnas 2005). This, together with M. rubra’s aggressive defense of invaded territories, has led to fewer native ants in infested areas. The purpose of this literature review is to investigate ant–homopteran relationships and discuss the possibility of homopterans indirectly aiding ant invasions.
