Males of both the lesser wax moth, Achroia grisella (F.) and the bush katydid (Insara covilleae Rehn and Habard), call mates with high-frequency sound audible to insectivorous bats. Both insects cease acoustical mate calling when they hear the cries of either an approaching bat or a similar artificially-produced sound. But, the lesser wax moth sometimes continues to call by producing pheromone, but not sound. Both insects resume acoustical calling either soon after a bat has passed or after the artificial sound is removed.
