Plectroctena mandibularis

Plectroctena mandibularis, called the ringbum ant or millipede munching ant,^[1][2][3] is a large species of ant that ranges from the Eastern Cape, South Africa, through East Africa to Ethiopia. Their workers forage singly^[4] in open terrain, and their colony size seldom exceeds fifty individuals.^[4][5] It is one of the large Plectroctena species, including P. conjugata and P. minor, that specialize on adult millipedes as prey.^[5] The nest is composed of chambers that are typically located two feet or more below the surface, and the nest entrances are usually marked by large piles of earth.^[4][5] They get their colloquial, common name from their tendency to prey on millipedes.
