As per the title, the full video by Anton Petrov is here https://youtu.be/MzL...sqwMf321OMQWHnD

 

TLDW, insects are not even attracted to lights, their mechanical responses to light are forcing them to endlessly circle around light sources. In other words, its torture.

 

Might get more push to non-astronomy environmental agencies and governments to reduce light pollution.

 

Thoughts?

Its their navigation mechanism. First operation is to get altitude

This mechanism has been well understood for a few thousand years or more. As long as their navigation azimuth angle to the reference moon is acute, that defines a constricting Cornu Spiral and disaster if some other torch confuses identification with Luna. Other animals also get confused by this. I researched Insect Vision with field work in the jungles of Panama for nearly two years. No kidding that artificial outdoor lighting kills off untold trillions of insects and billions of other animals in various other orders and species. Even fauna are not immune from this pandemic. Nor are we humans. Alas... most novice vogue ~environmentalists~ ignore wildlife in favor of their electric cars. In that sense, environmentalism has become more of a self-actualizing ~feel good~ schtick than any truly deep understanding or concern for our place in this unique little spherical abode.    Tom

It is a brave new world, which I abandon to the “brave.”

Known to me in the context of exterminating wasps at night. It's cool that you helped with the research.

Even for those that don't make the mental connection between insects and pollinators, and thus don't give a crap how many they kill, I read the BBC article from the research that said that shielded lower color temp LED's reduce the insect kills (and thus the swarming) by 70-80%.

So next time the rectal hat next door puts up a daylight color temp unshielded LED light you can tell them that if they were to shield it and lower the color temp it would drastically reduce the number of bugs, including mosquitos that they are attracting to their back yard.
