Caption: Endangered silversword plant. Single silversword plant Argyroxiphium sp. seen after flowering in Haleakala crater on Maui, Hawaii. This plant is native to the Hawaiian islands and is threatened by the alien invading Argentine ant (Iridomyrmex humilis). The silversword relies on insects to pollinate it, including the yellow-faced bee. The Argentine ant is a successful colonizer, and out- competes both native Hawaiian ants and insects which pollinate the silversword. In this way the reproduction of the silversword plant is affected. About 20 foreign insect and 5 foreign plant species are introduced to Hawaii each year. Alien invaders may destroy the ecology of a country.
