LED streetlights are decimating moths in England. The LEDs have blue light which insects use to see. The moths are pollinators like bees plus they’re food for many animals.
There are a number of solutions for mitigating the problem. The blue light can be filtered out, among other things.
My thinking is that the streetlights should be fitted with motion detectors that go on for maybe ten seconds when a vehicle approaches. During late night / early morning the traffic is so low that there will be very little LED light to attract insects. The LED lights can be dimmed to 1/4 or less brightness so they attract insects less but the dimming saves electricity.
