> To go back to the ladybugs, specifically the Asian ladybugs, last year they were everywhere. Every corner would have a bunch of them. They'd get in the house and then smash into the ceiling near every pot light leaving discolorations (blood or something). This year I've seen barely a dozen or so all season. It's just a complete 180.
To me, it sounds like your area experienced an intentional release of the Asian Lady bug last year. TBD if they kill off all your fireflies, obviously that's pure speculation on my part.
As far as firefly decline, I don't live on the edge of a city or town. I'm actually quite rural. There are two places I've seen the decline. My home and my family's cabin 2 states away, both very rural. There has been no significant habitat change in either area, both having forest and established farms, very little development over my lifetime.
This is not an effect I noticed gradually or recently. It was about 15+ years ago now. Fireflies basically just disappeared, all at once. The colors of the remaining fireflies in both locations are also different. They were previously a yellow-green glow, and have been replaced by a more white-bluish glow.
Anyway, I don't know what caused their decline, but it's very apparent, and light pollution has nothing to do with it in my area.
If your cabins are near farms it is very possible the firefly decline you possibly noticed was caused by the introduction of neonics in the 90s. They are incredibly destructive and are part of the reason for the european honeybee issues that have gotten so much press here in the US.
They are widely believed to be a major factor in the current decline of insects.
