Bugs don’t just materialize out of the ether to swarm lights. Not to feed swallows. They are there and you will encounter them if the density is much more than zero.

There are bugs. You photographed bugs. Maybe more than you would have without lights at all, maybe about the same.

Also better lights don’t necessarily mean perfect lights. We do lots of things to reduce harm. Unfortunately sometimes we do them too much and conserve a significant fraction of the original harm by increasing demand.
