These insects were the only organism found regularly in the early stages of the formation of the fairy circles. The grass root-eating sand termites reduced the grass growth in the vegetationless flats, according to jurgens. Other experts vehemently contradict the biologist.
Fairy circles occur in hundreds of thousands in the arid land near the southwestern coast of africa. Each of the points, drawn as if with a compass, is surrounded by a wreath of tall grass at a closer look. From the bird's perspective the red spots are almost priceless. With diameters up to about 20 meters, they give the impression that the earth had freckles.
