A male cricket sings love songs by rubbing his 2 front wings together. His lady fair hears the songs with ears on her front legs, but she never answers. A male cricket sings love songs by rubbing his 2 front wings together.
Some insects produce sounds by forcing air out of their bodies.
As the air passes through the moth's pharynx, the opening of its pharynx vibrates and produces sound. The faster it vibrates, the higher the pitch of the sound it produces. Try using a balloon to demonstrate how the death's-head moth produces sound. Hold the neck of the balloon between the first fingers and thumbs of both hands. Slowly stretch the neck of the balloon sideways as far as possible to form a narrow opening which lets the air out slowly.
