Drivers help study road-trip mystery: what became of bug splats?

Phys · · 538 words · By Victor POMMATAU
Environmental Decline/Biodiversity Loss Citizen Science/Public Participation

The article discusses a citizen science project in France, using a free app to track and count squashed insects on car number plates during road trips. This initiative is part of a broader effort to study the decline of insect populations, citing previous studies from Denmark and the UK that reported significant reductions. Scientists attribute this decline to human activities such as habitat loss, pesticide use, pollution, and climate change.

“Long an emblem of the summer road trip, squashed bugs on the car have become less numerous over the years, many people say—causing concern about the health of the world's insect populations.”
VERIFIED
The claim is supported by multiple web search results discussing the 'windscreen phenomenon,' which notes that fewer insects are found squashed on cars compared to previous decades. This trend is presented as a concern regarding insect populations.
