Over on the east coast of Florida they have "Butterfly World". It is the largest butterfly park in the world. If you love butterflies it is pretty awesome.
Scientists Discover Butterflies Originated in America 100 Million Years Ago When Upstart Moths Wanted to Bask in the Sun
Scientists completed a vast evolutionary jigsaw puzzle in 4D—and they discovered that butterflies originated in America around 100 million years ago.
They determined that it was a group of “trendsetting” moths that started flying during the day rather than at night, taking advantage of nectar-rich flowers that had co-evolved with bees.
That single event led to the evolution of all butterflies, and now scientists have discovered where they first originated and which plants they relied on for food.
Researchers have known the precise timing of the event since 2019, when a major analysis of DNA discounted an earlier theory that pressure from bats prompted the evolution of butterflies following the extinction of dinosaurs.
Before reaching their conclusions, researchers from several countries had to create the world’s largest butterfly tree of life, assembled with DNA from more than 2,000 species representing all butterfly families.
Using the framework as a guide, the team traced the movements and feeding habits of butterflies over time in a four-dimensional puzzle that led back to North and Central America.
“It’s something I’ve wanted to do since visiting the American Museum of Natural History when I was a kid and seeing a picture of a butterfly phylogeny taped to a curator’s door,” lead author Doctor Akito Kawahara, curator of Lepidoptera at the Florida Museum of Natural History. “This was a childhood dream of mine.”.............
.........“It’s also the most difficult study I’ve ever been a part of, and it took a massive effort from people all over the world to complete.”
There are more than 19,000 butterfly species, and piecing together the 100 million-year history of the group required data about their modern distributions and host plants.................
