Insect Splats Plummet: UK Faces Flying Insect Crisis
1 Jun
Summary
- Flying insect numbers fell by 62.5% between 2021 and 2024.
- A UK survey counts insect splats on car number plates.
- Habitat loss and climate change are blamed for insect decline.
A citizen science project in the UK has recorded a significant decline in flying insect abundance. The Bugs Matter survey, conducted annually each summer, asks participants to count the number of insect splats on their vehicle number plates after journeys.
Between 2021 and 2024, the number of recorded flying insects fell by 62.5%. While the rate of decline slowed between 2023 and 2024, this overall decrease is considered concerning. Scientists suggest it is likely due to a combination of long-term background decline and short-term cycles potentially linked to recent extreme weather in the UK.
Conservationists warn that such declines have catastrophic potential consequences, as invertebrates are critical for ecosystem functions. Human activities such as habitat loss, pesticide use, pollution, and climate change are identified as major contributors to this trend. Urgent action is needed to restore nature and heed the warning signs of ecological collapse.
