Summary
Our sensory systems are our access to the world. In an evolutionary arms race, bats and insects interact as predator and prey based on exclusively acoustic information. Using microphone systems in the lab and field, we investigate which information and sensory strategies bats use for hunting insect prey. To counter the prey’s defence systems, some bats became inaudible for their unsuspecting prey, while other species rely on the prey’s rustling noises or eavesdrop on the foraging calls of other close-by bats.
