UK Crisis: Two-Thirds of Flying Insects Vanish in Just Three Years!

Over a three-year period, the United Kingdom has seen a dramatic 63% reduction in its flying insect population. This was revealed by the “Bugs Matter” citizen science study on April 30.

The study, initiated by the Kent Wildlife Trust and Buglife, two environmental organizations, adopted a straightforward approach: from 2021 to 2024, thousands of British drivers were asked to upload pictures of their car number plates to a dedicated app before and after their journeys. The aim was to count the number of insects squashed on the plates. Over 25,000 trips were logged in this manner.

The findings confirmed what many had already observed visually—the noticeable decrease in insects on their windshields. These results align with similar studies conducted in other European countries. For instance, a study in Denmark showed an 80% decline in insect numbers from 1997 to 2017. The main causes identified include habitat loss and degradation, climate change, and pesticide use.

This decline is “truly alarming,” stated Dr. Lawrence Ball from Kent Wildlife Trust in a press release. “The implications are significant, not just for the health of the natural world but also for the many essential services that nature provides,” added Andrew Whitehouse of Buglife. For example, agricultural productivity suffers without insects.

According to Philippe Grandcolas, Deputy Scientific Director at the CNRS Ecology and Environment Institute, the situation is “partly reversible if we alleviate the pressures such as habitat loss and pesticide use.” The new Bugs Matter campaign for 2025 commenced on May 1 and will run until September 30. It is now open to residents of Ireland.
