Insect sounds help AI monitor environmental health

Researchers at the University of Massachusetts (UMass) Amherst have been hard at work figuring out just how well artificial intelligence (AI) can identify insects based on their sounds. It turns out, our buzzing little neighbors can tell us a lot about how the environment is doing.

Insects may be small, but these tiny creatures play a gigantic role in our ecosystems. But with climate change, pesticides, and other environmental pressures, insect populations are constantly changing. Tracking these changes is a huge challenge.

Why do insect sounds matter?

“Insects have an enormous impact on global ecosystems,” said Laura Figueroa, assistant professor of environmental conservation at UMass Amherst. “They provide a vital food source for countless other animals, including species as diverse as birds, fish, bears, and even humans.”

In addition, insects play critical roles in pollination, nutrient cycling, and other essential ecological processes. Despite their significance, tracking insect populations across large areas and understanding how they are being impacted by environmental changes is a significant challenge.

Role of AI in identifying insect sounds

Traditional approaches to insect monitoring often involve physically collecting specimens in the field. While these methods can provide accurate data, they have several drawbacks. Field collection can be labor-intensive, requiring significant time and resources.

Additionally, the process of collecting insects often results in harm or death to the organisms, which can be a concern for species that are threatened or declining.

The development of AI technology offers a potential solution to these challenges. By analyzing the sounds insects produce, AI models can identify and differentiate species without the need for physical collection.

Can a computer tell the difference between a honeybee and a mosquito? Figueroa believes so. “Since many, but not all, insects emit sound, we should be able to train AI models to identify them by the unique sounds they make.”

To explore this concept, the researchers analyzed numerous studies that used AI systems to identify insect species by sound. The models they examined spanned a range of complexity:

  • Non-machine learning: These systems search for specific sound characteristics that have been predetermined by researchers. For example, they might be programmed to look for a particular frequency range that’s common in a mosquito’s whine.
  • Machine learning: Machine learning models exhibit greater adaptability. These systems analyze sound data to discover patterns on their own, matching them against a database of known insect sounds for identification.
  • Deep learning: Deep learning represents an advanced subset of machine learning. These models leverage sophisticated neural networks that mimic the way a brain learns. This allows for even more accurate and nuanced identification of insect sounds. Some deep learning models have achieved over 90% accuracy in identifying hundreds of different insect species.

AI and the future of insect monitoring

“This doesn’t mean that AI can or should replace all traditional monitoring approaches,” noted Anna Kohlberg, who led the research on AI-insect identification. “Automated bioacoustics is a key tool in a multifaceted toolkit that we can use to effectively monitor these important organisms all over the world.”

AI-based insect monitoring, while promising, does have certain constraints. Many AI models require extensive amounts of sound data to be trained effectively. This can be a challenge when working with rarer or less vocal insect species.

Environmental factors such as background noise from wind, traffic, or other animals can impact the accuracy of AI analysis by masking or distorting the insect sounds of interest. Finally, not all insects produce identifiable sounds, meaning AI-based monitoring is unsuitable for certain species.pen_spark

Study significance

Understanding our insect populations isn’t just about knowing how many there are. It’s about seeing the bigger picture of environmental health.

A place without the buzzing of pollinators or the clicking of crickets might tell us that the ecosystem is struggling. With AI, we suddenly have a new way to listen to what nature is trying to tell us.

Potential applications of AI insect monitoring

The technology that leverages AI to detect and analyze insect sounds has a broad spectrum of applications, each offering unique benefits to science, agriculture, and conservation efforts. Here’s where and how this technology can be employed:

Environmental monitoring and conservation

  • Biodiversity studies: By identifying and tracking the presence of various insect species through their sounds, researchers can assess biodiversity in different habitats. This helps in understanding the impacts of environmental changes and human activities on ecosystems.
  • Conservation efforts: Monitoring endangered or invasive insect species through their sounds allows for targeted conservation actions. It helps in creating strategies to protect endangered species and control the spread of invasive ones.


  • Pest management: AI-driven sound detection can identify pest species early, allowing for timely pest management actions. This reduces crop damage and can decrease the reliance on chemical pesticides, leading to more sustainable farming practices.
  • Pollinator health monitoring: Tracking the sounds of pollinators like bees can provide insights into their health and behavior. This is crucial for maintaining healthy pollinator populations, which are vital for crop pollination and agricultural productivity.

Public health

  • Vector control:Researchers can monitor mosquitoes and other disease-vector insects through their sounds. This technology can assist in controlling populations of disease-carrying insects, reducing the spread of illnesses like malaria and dengue fever.

Scientific research

  • Behavioral studies: Understanding the communication and mating calls of insects can offer insights into their behaviors and social structures. This enriches our knowledge of entomology and helps in developing new strategies for insect management.
  • Ecological impact assessments: By monitoring changes in insect populations and their behaviors through sound, scientists can assess the ecological impacts of climate change, habitat destruction, and pollution. This information is critical for developing strategies to mitigate negative impacts on the environment.

Citizen science

  • Engagement and education: Engaging the public in monitoring insect sounds through AI can raise awareness about biodiversity and conservation. It also provides valuable data for scientific research, fostering a collaborative effort between scientists and the community.

Employing AI to detect and analyze insect sounds harnesses the power of technology to address some of the most pressing challenges in environmental conservation, agriculture, and public health.

By translating the whispers of nature into data, we can make informed decisions that protect and preserve the natural world for future generations.
