Abstract:

Next to Psammotermes allocerus, Hodotermes mossambicus (known as Northern harvester termite) is the most frequent termite in the fairy circle landscapes receiving summer rains. Both species sometimes share the space in the soil at distances of few decimetres. Often the soil dumps of Hodotermes are even found within a fairy circle bare patch. The co-existance indicates niche differentiation. In fact, the foraging behaviour of both species is very different. While the small Psammotermes colonies forage in the matrix around the bare patch and initially prioritize subterranean biomass, Hodotermes is active during the day, first collects litter and then harvests grass tussocks from the top downwards. During the peak vegetation period large numbers of Hodotermes workers are rapidly cutting grass culm segments and sometimes also fresh green leaves of dicots and carry them to the foraging port, where too large segments are rejected and finally remain in star-shaped pattern around the foraging port.
