During the season in different points of the bush cricket breeding population there repeatedly appear and disappear groups of calling males - choruses. The model is proposed to explain the dynamic aspect of spacing. According to this in each male the optimal level of social stimulation changes m time: the periods of intense desire for social stimulation are followed by periods of desire for notation. The model was tested on 5 males, kept in isolated cages arranged so as to form a star pattern. The analysis of spatial distribution and vocal activity of those males during one season revealed that behavior of the males 1 — is not contradictory to the one predicted by the model, and 2 — refutes the alternative models, presuming the level of social stimulation to be constant.
