How many insects are wind turbines killing?

An amateur study published in PLOS ONE "More than 75 percent decline over 27 years in total flying insect biomass in protected areas", claims a massive fall in German insect populations. Germany has the highest density of wind turbines in the world.

When we add another column showing wind capacity per 1000 km² we see Germany has the highest density of wind turbines per area. Twice UK.

Dr. Franz Trieb of the Institute of Engineering Thermodynamics concludes that a "rough but conservative estimate of the impact of wind farms on flying insects in Germany" is a “loss of about 1.2 trillion insects of different species per year” which “could be relevant for population stability.”

This was all too predictable: build wind-turbines all over the world and expect no affect on flying animal populations. <-- Only activists could be so dim. Now greens are mostly ignoring the study is in Germany, which has the most wind turbines. Greens are blaming it on global warming or environmental destruction due to capitalism. Anything to keep themselves out of the dock.

Note: Most land-based wind-turbines in UK are in Scotland. Most wind-turbines in UK are probably offshore in the North Sea. PS: This sentence is entirely subjective, and an aside; if I think it matters I will calculate it.
