Insect. An incredibly successful colonizer capable of invading both disturbed and undisturbed habitat , the Argentine ant can produce large numbers of aggressive workers. It is an economic and ecological pest, affecting agriculture, displacing native arthropods , and potentially altering ecosystem processes. It has formed the world's largest colony in South Europe, where it´s invasive.

Species Linepithema humile
Member of the subfamily Dolichoderinae. Workers of this species are small, medium to dark brown ants , reaching 2 to 3 mm in length . Body surface is smooth and shiny and lacks hairs on the dorsum of the head and thorax. The petiole is composed of a single, scale-like segment, and sting is absent. Workers are extremely fast moving and industrious, often recruiting in high numbers.
As this species is very widely distributed, information listed on this site pertaining to invaded habitat types around the world is likely incomplete or in some cases inaccurate. We invite the numerous researchers working with this species worldwide to rectify any omissions or inaccuracies.
Typically found at an altitude of 0 to 4,653 meters (0 to 15,266 feet).
Ecology: In favorable habitat , the Argentine ant can reach high densities and exclude nearly all native and introduced ant species (e.g. Majer, 1994; Cammell et al., 1996, Human and Gordon, 1996; Holway, 1998), substantially reduce non-ant arthropod abundances (Cole et al., 1992; Human and Gordon, 1997), and potentially alter ecosystem-level processes such as seed dispersal and plant pollination (Christian, 2001; Cole et al., 1992; Visser et al., 1996).
Sexual, haplodiploid system
.Varies according to environmental conditions
and probably demographic
Virgin queens are believed to mate in the nest and disperse through budding rather than participating in a nuptial flight, resulting in the formation of large, many-queened, cooperating unicolonies (Markin, 1968). Queens may be executed by workers after one year and replaced by newly mated queens (Markin, 1970; Keller et al., 1989).
