As we know, Darwinism is an ever-evolving theory, so its devotees will undoubtedly manage to come up with another convoluted corollary for this recent discovery ~

New fossil evidence puts the squeeze on Darwinians, making butterflies appear suddenly, with complex mouth parts, before there were any flowers to pollinate […]
 
Moths and butterflies existed during Jurassic era, millions of years before flowering plants, team reports (Science Daily). “A team of scientists report on new evidence that primitive moths and butterflies existed during the Jurassic period, approximately 50 million years earlier than the first flowering plants, shedding new light on one of the most confounding cases of co-evolution.” It wasn’t co-evolution, though, if butterflies lived just fine for 50 million Darwin Years before the plants they were supposed to co-evolve with first appeared.
 
The Oldest Butterflies on Earth Had No Flowers to Feed On (Live Science). “Some of the fossils share features with modern moths in the suborder Glossata, which have a straw-like proboscis that can suck up fluids like nectar,” writes Darwinist reporter Laura Geggel. “Given their complexity, and the time it would’ve taken to evolve to have such complex features, these fossils push the calculated age of glossatan moths back by about 70 million years to the Late Triassic ‘refuting ancestral association of the group with flowering plants,’ the researchers wrote in the study.”

 
So according to the Darwinists, these fully-evolved, modern-looking butterflies appeared 200 million years ago (millions of years before there were any flowering plants) – and no transitional versions of these insects have ever been discovered. Hmmm…
