I'm sure many macro photographers are aware of this. I noticed it several years ago and it's only getting worse.
There seems to be a decrease in all lifeforms, except that pesky human race, of late years.
But, that is not the reason for less around lights.
Parking lights were mercury vapor until the true poisoness nature of the metal was better known.
This was a good thing, not just to get rid of the poison.
The wavelength emitted by Mercury vapor lights attracts insects of all types, disrupting their normal doings.
Moths were at a low because they were not mating, but being eaten by bats, birds, mice, rats, you get the idea, because the lights attracted and trapped them more than pheromones.
Lighting, and the wavelengths are not near as distracting today.
Now the danger is more pesticides and habitat distruction.
Those pesky humans again.
Of course, they are my favorite people, for the most part.
