The temporal relationship between male-calling and female-walking of Teleogryllus ocearicus has been studied. Both behaviors are under circadian control. A comparison of singingactivity under controlled environmental conditions and in the field at LD 13.75:10.25 h revealed that in spote of the very different situations, calling occurred during darkness; the times of onset, termination of singing and the calling quantity agreed as well. However, significant individual differences in singing activity were observed in either environment, and for specific males on consecutive nights.
