Do Moths Make Noise? The Surprising Truth Revealed

When most people think of moths, they think of the pesky bugs that fly around lamps and porch lights at night. But did you know that moths actually make noise? It may come as a surprise to you, but moths have the ability to produce a variety of sounds, from gentle fluttering to loud, high-pitched chirps.

What Causes Moths to Make Noise?

Moths are known for their whisper-quiet flight, but certain species are capable of making noise by rubbing their wings together. This is known as stridulation, which is the process of producing sound by rubbing two body parts together.

In the case of moths, the males are the ones who produce the most noise. They do this by rubbing together their wings or other body parts that have specialized structures called “stridulatory organs.” These organs are often located on the lower edge of their wings, and the males will rub them together to create a musical sound.

Why Do Moths Make Noise?

While there is no definitive answer as to why moths make noise, it is believed to serve a few different purposes. One of the main reasons is for courtship and mating. The males use their sound-producing abilities to attract females by creating a unique, distinctive sound that catches their attention.

Another reason why moths make noise is for communication. Moths use sound as a way to communicate with other moths, often warning them of potential dangers or signaling that they have found a food source. Some species of moths even use sound to defend their territory, using loud chirping sounds to ward off other males.

How Loud Can a Moth’s Sound Be?

The loudness of a moth’s sound depends on the species and the specific sound being produced. Some moths produce only a gentle fluttering sound, while others can create a noise over 100 decibels (dB) in volume, which is equivalent to the sound of a jet engine or a loud rock concert.

It’s important to note that most moth sounds are not audible to the human ear. Moths produce sounds primarily in the ultrasonic range, which means they are too high-pitched for us to hear. However, scientists can detect and analyze these sounds using specialized equipment.

Which Moth Species are Known to Make Noise?

While not all moth species have the ability to produce sound, there are several that are known for their sound-producing abilities. Some of the most well-known species include:

  • The African Death’s Head Hawkmoth
  • The Luna Moth
  • The Rosy Maple Moth
  • The White-Lined Sphinx Moth
  • The Polyphemus Moth

Each of these species has unique stridulatory organs that produce a distinctive sound, ranging from soft, fluttering sounds to loud, high-pitched chirping.

Can Moths Be Identified by Their Sound?

While it is possible to identify some moth species by their sound, it is not always easy or reliable. Moth sounds can vary depending on a variety of factors, including the moth’s sex, age, and location. Additionally, some species of moths produce very similar-sounding noises, making it difficult to distinguish between them.

However, some scientists have developed tools and techniques that can help identify moths by their sound. This can be particularly useful for studying moth populations and behaviors in the wild.

What Other Insects Make Noise?

Moths are not the only insects that can make noise. Many other species, such as crickets, grasshoppers, and cicadas, are well-known for their sound-producing abilities. In fact, some of these insects can produce sounds that are even louder than a jet engine.

One of the most famous sound-producing insects is the cicada, which is known for its loud, buzzing noise that can be heard from miles away. Cicadas are also unique in that they produce their sounds using specialized organs called tymbals, which are located on their abdomens.


So, do moths make noise? The answer is a resounding yes – certain species of moths are capable of producing a variety of sounds, from gentle fluttering to loud, high-pitched chirps. While not all moth sounds are audible to the human ear, their sound-producing abilities play an important role in their communication, courtship, and defense strategies.
