A Seventy-five percent Decline in Bugs?

This story of noticeably fewer bugs on the car windshield was something I mentioned at least five years ago in one of my reports from personal observation following a visit driving across the state of Nebraska to Eastern Nebraska farm country. When I was a child, there were so many! We are well on our way to sterilizing farm country. But, not just in the U.S.

More than 75 percent decline over 27 years in total flying insect biomass in protected areas
...we used a standardized protocol to measure total insect biomass using Malaise traps, deployed over 27 years in 63 nature protection areas in Germany (96 unique location-year combinations) to infer on the status and trend of local entomofauna. Our analysis estimates a seasonal decline of 76%, and mid-summer decline of 82% in flying insect biomass over the 27 years of study.
