Multi-sized ants from 4 to 8/9mm, slow moving harvesters of vegetable detritus. They move with a typical slow, 'bumbling' gait in trails and the trails have a curious habit of ‘freezing’ if you thump the ground next to them. Live in large colonies excavated around the base of bushes or in tussocks. Observed hard at it collecting bits of veg near a windpump in the Tankwa National Park. These ants are seed predators, not seed distributors. More at www.ants.org.za
