France launches citizen science initiative to track insect decline

French researchers, led by the National Museum of Natural History, have initiated a citizen science project titled "Bugs Matter" to monitor the decline in insect populations. Launched in April 2026, the initiative utilises a dedicated mobile application that invites car drivers to record dead insects found on their windshields. The project aims to generate France’s first comprehensive assessment of insect populations, addressing global concerns regarding biodiversity loss.

The National Museum of Natural History is coordinating the effort to gather large-scale data through public participation. By asking motorists to count the number of insects struck by their vehicles, the museum seeks to establish a baseline for understanding the scale of biodiversity loss often described as the "insect apocalypse". This approach allows for the collection of widespread geographical data that traditional scientific surveys may struggle to capture.

The mobile application serves as the primary tool for data submission. Drivers are instructed to use the app to log their findings, which will subsequently be analysed by researchers. While the specific metrics or methodology used by the app to convert windshield counts into population decline estimates are not detailed in the source, the initiative is described as the country's first ever comprehensive assessment of insect populations.

This project is part of the "Down to Earth" series reported by France 24. The report, published on 26 May 2026, highlights the call for public assistance in measuring these ecological changes. The museum’s involvement underscores its role as a leading institution for biodiversity research in France, leveraging citizen science to address environmental monitoring challenges.

The scale of participation and the initial volume of data collected are not yet provided. Furthermore, the exact timeline for the completion of the comprehensive assessment remains unspecified. The link between windshield counts and precise population decline metrics is a scientific model, meaning results should be presented as estimates rather than absolute facts. The initiative represents a significant administrative effort to quantify environmental shifts through structured public engagement.
