Back in the day, I was told that insects would navigate by the light
of the moon. And since a light bulb was closer and brighter they
would circle around it and spiral in until they were right on the
light. I'm not sure I both that though. My next question was to
where the insects were navigating?
It would seem to me though that once man could make fire at will, the
insects would fly into that and die. Yet this seems to have no impact
on evolution.
Oddly enough, look at the things that were once beneficial
evolutionary traits that are now detrimental.
In times past if you could store a majority of the calories you ate as
fat, you had a better chance of survival. Now, it will kill you.
I'm sure there are many more.

Although I'm not an expert on insect vision, I can say that they see in
ways you can't imagine: their vision peaks at 350 nanometers, way into
the ultraviolet and they are effectively blind to yellolw and red
light.
OK, I am going to change tubelight and I will use yellow or red light
tonight. Let me see whether I keep this moth menace away.
They've sold yellow light bulbs for those who don't want to attract
moths for as long as I can remember.
Hanging a red light outside your front door may have connotations
different from what you might want.
It might be more lucrative than attracting moths to your front door,
though...
