Overview
Students in the 21st Century Biology Class at Sidwell Friends school are currently studying leafhoppers, common insects found in most lawns, and their forms of communication. By sending vibrations through substrate, such as grass, stems, and leaves, these insects are able to form a unique method of communication.
Current Experiments
By constructing a recording device from a phonograph needle, the vibrations in substrate can be converted to an electrical signal that can be displayed on an oscilloscope and heard through a speaker. This device transduces the insect vibration to a sound that can be perceived by the human ear. We are currently studying the forms of communication utilized in mating and raising young, finding food, and escaping danger.
Future Projects
Future experiments include the study of the five different forms of sounds used by insects (stridulation, clicking, percussion, air expulsion, vibration) and the possible reproduction of these sounds back to the insects.
