The air vibrates with insect song, a symphony of buzzes, clicks, and whirs that defines summer for many. Amidst this natural orchestra, a common question arises: Do Cicadas And Locusts Sound The Same? The answer, in short, is no. While both insects are capable of producing sound, the mechanism, purpose, and resulting sound are distinctly different.
The Sonic Secrets of Cicadas and Locusts
Understanding why cicadas and locusts sound different requires a look at how each insect creates its unique call. Cicadas are the virtuosos of the insect world when it comes to sound production. Their method is unique in the insect world, which helps to create a very distinctive sound. Instead of rubbing body parts together, as many insects do (like crickets), male cicadas possess specialized organs called tymbals. These are located on their abdomen and are essentially ribbed membranes that buckle and click when muscles contract, producing a loud, buzzing or clicking sound.
Several characteristics define cicada sound production:
- Tymbals: The primary sound-producing organs.
- Resonating Chambers: Hollow abdominal cavities amplify the sound.
- Male-Specific: Only male cicadas produce these loud calls.
This complex system allows cicadas to generate sounds that can reach impressive decibel levels, sometimes exceeding 100 dB, comparable to a lawnmower! The purpose of this sonic display is to attract mates. Each cicada species has a distinct song, allowing males to attract females of their own kind.
Locusts, on the other hand, create sound through a process called stridulation. This involves rubbing one body part against another. Typically, they rub their hind legs against their wings, producing a chirping or buzzing sound. The sound produced by locusts is generally much quieter and less complex than the calls of cicadas. It serves primarily for communication within the swarm, helping them to stay together and coordinate their movements.
| Feature | Cicadas | Locusts |
|---|---|---|
| Sound Production | Tymbals (buckling membranes) | Stridulation (rubbing body parts) |
| Sound Volume | Very loud | Relatively quiet |
| Primary Purpose | Attracting mates | Communication within swarm |
