Earlier quoted context omitted.

Insects can see ultraviolet light but not red.

I'm no expert on the matter, but that seems like a pretty sweeping generalization.

From a cursory review of results for "insect visual spectrum" it seems to check out - quite useful to know.

It probably won't save the world, but we developers sure could do more to save energy and not requiring ridiculous hardware resources for what seems like merely gradual improvements over the 90s, with all the chemicals for processing and in batteries, and with all the waste. By this time, we could've achieved long-lived solar-powered mobiles with B/W LCDs. I remember text processing software being pitched as paper-saving devices.

Years ago, my family used to drive to our grandparents' village in hot, summer Friday nights. The windshield ended so pestered with dead bugs that the first task on Saturday morning was to drive the car to the river to clean it. I remember it vividly because it was so fun to wash the car with the cold river water. Last August I went stargazing with my wife. We chose a secluded area because it was far away from light…

>> I hate mosquitoes as much as everybody else, but something has been happening to insects in the last 20 years.

Whatever it is, it's not happening to mosquitoes. This entire summer I had at least 5 of them buzzing around my head every night- and I did swat at least half of them each evening.

My dad claims that the bugs come and go in cycles and says he has seen so several times over his life. He believes that we are just in a period of low bug population and that at any time there could and will be a population explosion. Personally I am not so optimistic. My dad moved around multiple times over his life and I would suspect different areas would naturally have varying bug densities and that is why he fel…

For what it's worth, i noticed the same bug-on-windshield difference between the 80s and now in France. So, whatever it is, it crossed the Atlantic ocean.

I have similar memories from my childhood in the 80's. We lived in Savannah and would make the trek to North Georgia several times a year to visit my mom's family. I can remember the headlights illuminating a sea of bugs like a light snow and the bigger ones popping loudly on the windshield from time to time. Having a full reservoir of wiper fluid was crucial and my dad would let me scrub the windshield whenever we s…

Same thing in Sweden, summer nights, 80s. Today, I never have that problem, not even during this humid, record hot summer.

I'm pretty sure this is more related to a rather radical shift to a more industrialised agriculture the recent 40 years.

Grazing land and more importantly meadows are simply gone. According to Wikipedia, England and Wales have lost about 97% of their hay meadows. Meadows are artificial, but they increase the biodiversity significantly.

Neonicotinoids are probably also to blame.

Climate change must be negligible in comparison, but it seems that everything can be blamed on climate change. War in Syria for instance.

re: "Lister and Garcia attribute this crash to climate. In the same 40-year period as the arthropod crash, the average high temperature in the rain forest increased by 4 degrees Fahrenheit. The temperatures in the tropics stick to a narrow band. The invertebrates that live there, likewise, are adapted to these temperatures and fare poorly outside them; bugs cannot regulate their internal heat." No doubt, this is alar…

Have any of these studies found places where insect populations have not declined at all?

L.A. has gotten new-improved mosquitoes recently:

Flying insects are generally attracted to light. Our cities and vehicles generate light particularly during the night drawing them away from more-ideal habitat and often to their death on windshields. Now it is a fair point that this wouldn’t matter if there were thousands or even a few million vehicles but consider there are over 1.015B vehicles active on the road today and billions of us living in brightly lit cities.

Why does it come as a surprise that we are bleeding this planet dry?

Stop having kids and consider dying early.
