When people around here mentioned there are no more insects on the wind screens of car a local biologists checked the number of insects - and it was more or less the same (~5% less)
But what he found out was pretty interesting: Nowadays insects avoid streets. Evolution seems to have breed an inherent fear of streets into insects.
I’ll believe you without questioning or researching myself because that would be a very comforting thought indeed
You would believe it if you saw the mosquito swarms in my garden. The quite busy street basically is a biological desert. One meter off road in my garden I have a HUGE swarm of mosquitoes every evening. Not just one or two, more like 100, all in one big flock, within 1-2m³. And as soon as I leave the house they are all over me. Only way to get rid of them: Walk to the street or get back into the house. Dusk-Time is Mosquito Time in my garden. No humans allowed.
Edit, what I call mosquitos are two different insects around here. The very tiny ones of 3-5mm and sting like hell and the huge ones at 50-150mm (Not joking, some are larger than my hand) which are utterly harmless but also disgusting. I guess nobody expected Monster Mosquitos in Bavaria. But then we also have snakes who can spray like skunks. And LOTS of them.
Huge ones I bet are: https://en.wikipedia.org/wiki/Crane_fly
