Which structure is responsible for sound production in Cicadidae?

• A. Tymbals
• B. Wings
• C. Antennae
• D. Ocelli

Answer: (A)

Sound production in cicadas comes from tymbals, paired sound-producing membranes located on the sides of the abdomen. When the tymbal muscles contract, the tymbal membrane buckles back and forth extremely rapidly, creating a pulse of sound. Repeating these buckling cycles produces the loud, distinctive chorus that male cicadas use to attract females. The organism’s body acts as a resonator, helping to boost the sound so it can carry over distance. Wings aren’t the source of the sound in cicadas—though wings are important for flight and other functions in many insects. Antennae are sensory structures for smell and touch, not sound production, and ocelli are simple eyes for light detection.
