Due to these rapid transitions, human observers may see the grasshopper as appearing and disappearing instantaneously. Additionally, during flight, the hindwings transition ~6 times per second between pauses and periods of active wing-beating, during which the wings beat over 30 times per second.

The male sits horizontally on sunlit bare ground and may continue to stridulate for 5 minutes or more until he is successful in attracting a female.
