A group of scientists in Denmark enjoys counting the number of dead insects on the windshield. good on them. Everyone needs a passion.

They came to the conclusion: the number of insects in Denmark is shrinking. It appears to be happening elsewhere, too.

down 80% in one study

The Washington Post explains that from 1996 to 2017, Professor Anders Muller of the University of Paris-Saclay drove a car along the same road on the Danish peninsula of Jutland. He counted the number of bug spots each year.

Results? The sudden insect death rate was reduced by 80% along one of its roads and 97% along the other.

Muller used a series of rental cars (the world has ever published a list), so it’s possible that the cars’ aerodynamic improvements could explain some of the difference.

Car designers: This is not aerodynamics

But Kevin Gulch, an auto designer who works in the auto industry, told the Washington Post that’s unlikely. “A lot of studies have been done on sensor contamination, especially for self-driving vehicles,” Grolsch said. “And I think most people have given up trying to influence what happens at the car level with dust, particles and rain.”

Raindrops are often heavier than insects. If the windshield can’t push it out of the way, it probably can’t push the bugs out of the way either.

A similar study from England solved the wind tunnel problem by counting bug spots on license plates – the only part of the car that will probably never be aerodynamic. There the researchers found a 50% decrease in the total number of circuits between 2004 and 2019.

Wired reports, “The research included older cars up to 70 years old to see if their less aerodynamic shape meant they killed more bugs, but they found that newer cars actually caught a bit more bugs.”

lesson for you? We told you there wouldn’t be one. But it is not your imagination. It seems that the number of insects in the world is declining. Our clean windshield is proof.
