It’s both impressive and incredibly nerdy that scientists actually noticed the difference between the butterflies that are the actual species and the other species that mimic them almost exactly. Like how long did it take them to notice the difference? How many did they have to watch or dissect?

I've said it before and I'll say it again … your videos should be required watching in high school biology. Now, is there a way we can get that going? Would absolutely suck even jocks into science.
It's biology and physics all in one and you have managed to simplify that into something that everyone can understand. If you tried, by addressing HS biology and physics teachers, you could single handedly change education.

Interesting. I always wondered how these frail little creatures survive. They seem so vulnerable and defenseless.
They might seem ridiculous and defenseless to us because of our powerful color vision and high visual acuity combined with our strong rational thinking but other animals don't have that and will often fall for the disguise or defense colors and patterns.
Nature is fkin lit, moths using stealth coatings and active countermeasures just like an F-35.
