Something which I've also anecdotally noticed long before I researched it to confirm it's not my imagination. You can see it in action at my cousin's farm. Their prairie is a hive of activity and lights at night. The neighboring soy farm is dead.
I noticed fewer bugs on my windshield and called it _highly subjective_ statistics, already implying it proves nothing.
By coincidence I drive the same car as my mother did back then. And the same route. I will call it a standardized test then and wait for further peer review.
But the argument about windshield proves nothing.
