UK scientists fear insect loss as car bug splats fall

LONDON: A UK-wide decline in bug splats recorded on car number plates indicates an “alarming” fall in the number of flying insects, UK scientists said in a survey published on Wednesday.

The 2024 Bugs Matter report revealed the numbers of flying insects found stuck to vehicle number plates had dropped by nearly 63 percent since 2021.

Flying insects play a vital role in maintaining a healthy environment, as a food source for birds and other wildlife species, as well as acting as pollinators for crops and keeping pests under control.

The survey, led by Kent Wildlife Trust and charity Buglife, relies on citizen scientists who log their journeys and record the number of insect splats found on the front number plate of their cars.

Analysis of more than 25,000 journeys showed a sharp decline in splats across the UK between 2021 and 2024.

This included a 44-percent drop between 2022 and 2023, slowing down to an eight percent decline from 2023 to 2024.

“This huge decrease in insect splats over such a short time is really alarming,” said Lawrence Ball, a conservation scientist at Kent Wildlife Trust.

According to Ball, the decrease is a result of a general-long term decline in insect numbers compounded by a short-term decline which is “perhaps linked to the extreme climate in the UK in recent years”.
