Tienen toda la pinta, sí.

E, infelizmente, ouvi falar que o Portugal é cheio desta praga!

Pressuponho então que nao são nada benéficas. não é assim? sao do género de destruir colheitas?...
Por alguma razão fez essa afirmação.. até parece que são umas "Chatas"...

Taxonomic name: Linepithema humile (Mayr, 1868)
Synonyms: Iridomyrmex humilis (Mayr, 1868)
Common names: Argentine ant (English), Argentinische Ameise (German), formiga-argentina (Portuguese-Brazil)
.....

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.
.....

General impacts
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).
