  • Brachymyrmex patgonicus are also known as the dark rover ant. They are native to south America in particularly Argentina and Paraquay. Generally, this species is small but mighty Queens are usually 3mm in length and workers range from 1-2mm long. In the wild this species is observed visiting extrafloral nectaries for a source of nectar.

    Most invasive species tend to have polygyny tendencies and dispersal by budding and the development of super colonies that contain 100s of reproductive queens. However, the colony structure of Brachymyrmex patagonicus is different the nests generally consist of single queen in 80 percent of wild nests and there are strong genetic differences between the nests in addition they do have muti queen tendencies, but those tendencies are not as strong as other species.

    What’s more interesting is they have co-existing tendencies with highly invasive species like solenopsis invicta, so in theory they could be kept with other ant species without issues.
