I'm extremely unqualified, but is it possible that the insects just learned to avoid the specific traps used to do the measurements over time?

#17Presumably this is similar here in the U.S.? In the 80's and 90's the fronts of our cars would get so encrusted with mashed bugs that it would take real scrubbing to get them off. I haven't had to do that in many years.
I have heard this before. I’m not a climate change denier. Could it have anything to do with more aerodynamic car designs?
Now it rarely happens.
And with the last 2 cars I've had, I know it's not an aerodynamic issue because one of my hobbies is to do track days.
I go to Michelin's wet track something like once a year and it's bugs' paradise: fields, grass all around and very humid because the track is wet so you can hydroplane easily. Bottom line is my car gets plastered there and we don't even drive that fast (something like 80/90 km/h or 50/55 mph).

#18Are there large enough areas of the country that you could control for areas that don't spray for mosquitos to see if the populations have also declined in those areas?
It wouldn't surprise me at all to find out that the spraying over the last 10 years to control the mosquito population due to the media induced West Nile panic followed by zika panic has contributed to this.

#19Not sure, I have been wondering ( Europe) why new bugs appear that I have never noticed before. Butterflies are less also
