The distribution pattern of a population of the cricket Strinatia brevipennis was studied in a cave in Southeastern Brazil. The individuals do not move very often, but the population, as a whole, changes position along the day and night. Although the crickets never leave the cave, they approach the entrance during the night for fee ding. During the day, they return to the deep regions and remain almost motionless. The migration seems to be related to light intensity but not to temperature or relative humidity. A photophobic response is slightly evident but the possibility of the presence of an endogenous control of both, sensitivity to light and activity, must also be considered. |
