Name: Argentine Ant (Linepithema humile)
Scientific Classification and Taxonomy:
Distribution: The native range of Argentine ants is limited to around major waterways in the lowland areas of the Paraná River drainage. They have recently spread into parts of Argentina, Brazil, Chile, Colombia, Ecuador, and Peru. The species has become established in at least 15 countries throughout the world, on six continents, as well as many oceanic islands.
Reproduction: Like workers in many other ant species, Argentine ant workers are unable to lay reproductive eggs but can direct the development of eggs into reproductive females; the production of males appears to be controlled by the amount of food available to the larvae. Argentine ant colonies almost invariably have many reproductive queens, as many as eight for every 1,000 workers. The queens seldom or never disperse in winged form. Instead, colonies reproduce by budding off into new units. As few as ten workers and a single queen can establish a new colony.
