The Argentine ant (Linepithema humile, formerly Iridomyrmex humilis) is an ant native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil. [1]
Their native distribution rage from northern Mexico, east into the Caribbean, and south into northern Argentina. Two species have been spread around the world by human activities: L. iniquum and L. humile. The latter is better known as the Argentine ant, an invasive species with notable presence in Mediterranean climates.
Ant nests" are the physical spaces in which the ants live. These can be underground, in trees, under rocks, or even inside a single acorn. [6] The name "anthill" (or "ant hill") applies to aboveground nests where the workers pile sand or soil outside the entrance, forming a large mound. [10]
The Argentine ant (Linepithema humile), forming megacolonies of spatially separate nests, was thought to be a perfect example of unicoloniality, never exhibiting multicoloniality. [ 8 ] Giraud et al.

The ants counter this by preventing meat ants from leaving their nest by blocking their nesting holes with debris, a behaviour known as nest-plugging. [70] [71] If meat ant nests are encroached by trees or other shade, banded sugar ants may invade and take over the nest, since the health of the colony may deteriorate from overshadowing. [72]
