Twenty-two sound fields of calling males were measured under field conditions. Total power output ranged from 1.9 to 22.4 uWatt and was positively correlated with male size and soil moisture. Efficiency of sound production was only 0.02 to 0.16 percent. The shape of the sound field approximates a hemisphere. Lifetime oviposition by caged, individual female mole crickets was monitored outdoors. Oviposition is highly seasonal, and females that mature i...
