How the Green Lacewing Avoids Bats: Behavior and Physiology
Bat sonar systems are primarily used for avoiding obstacles and detecting prey. But, not all prey are deaf to the ultrasonic cries of bats. Members of two orders of insects, namely the moths (Lepidoptera) and the green lacewings (Neuroptera), have evolved mechanisms for detecting and avoiding bats. In this poster I will present the results of studies designed to investigate the avoidance behavior of freely flying green lacewings (Chrysopa carnea) to hunting bats and the physiological mechanisms underlying this behavior. Detailed accounts are found in Miller and Olesen (1979) and Olesen and Miller (1979).
