I came across this website, Top Documentary Films and this video, The Insect Apocalypse, produced by the German, DW Documentary Series in 2019. It gives a good overview of the causes and consequences of global insect declines, including the long-term German study, one of the first to provide real field data. We've all probably noticed the "windshield" effect with fewer flying insects ending up on windshields on summer drives. Well worth a watch. Searching the site for "insect" also returns some other interesting looking insect documentaries. topdocumentaryfilms.com/insect-apocalypse/

I watched the exact documentary on CuriosityStream, it was interesting, the windshield "test" was an unusual way of measuring population,, but certainly a simple one, and a simple way of of making people think.

My problem with such “ studies “ is they are often not based in science . Now I have not read this study but if that is the basis of a conclusion I don’t buy it . Reminds me of studies saying people who regularly eat almonds have a lower incidence of heart disease. Well Iam sure they do . However people can afford to eat cashews are likely wealthier and consequently have better and more frequent access to regular health care etc etc . Bottom line is way too many variables to make conclusions.

Bottom line is way too many variables to make conclusions. The German study that was published 2017 measured the collected biomass of insects over a long period of time and did so at specific places. Seasonal effects were taken into account. In pretty much every single place measured, they observed a steep decline in the biomass. The article only has a discussion and not a conclusion. You can read the study here, for free: journals.plos.org/plosone/article?id=10.1371/journal.pone.0185809
