Females of the digger wasp Liris niger Fabr. hunt crickets to provide food for their offspring by running with high velocity on the ground (>20–50 cm/s). Crickets are able to detect the running wasps by the air particle movement generated by the predator. We measured signals produced by running wasps using a microphone sensitive to air particle velocity. The wasps generated single air puffs with peak air particle velocities of 1–2 cm/s measured close to the running wasp. We measured frequency… CONTINUE READING
