Biology

Sorger et al. (2016) - Lepisota incisa has been reported from Kruger National Park, South Africa, where it is thought to have arrived in the 1990s (Sithole et al. 2010). There the species is most abundant in habitats associated with human disturbance and development, where it is behaviorally dominant to all other ants, including endemics. Judging from the slight, if any, aggressive response toward ants transferred between sites hundreds of kilometers apart around Kruger (Caldera 2004, cited in Sithole et al. 2010), it appears that Kruger is occupied by a single supercolony—presumably derived from the initial invading colony that arrived and spread widely within a region previously uninhabited by the species. At a single site, however, the workers were hostile to con-specifics from elsewhere in the park (Sithole et al. 2010), indicating that a second supercolony may have become established.
