Hilarious hedylids

This is a hilarious "nerd article" from Wikipedia, dealing with a group of "American moth-butterflies" (!!!) known as the Hedylidae. Apparently, these lovely little critters (35 species) look like moths but are butterflies. Or is it the other way around? And why would anyone even give a damn? 

The sources cited have fantasmagorically boring titles such as "Elusive ditrysian phylogeny: An account of combining systematized morphology with molecular data (Lepidoptera)" or "Creataceous origin of repeated tertiary diversification of the redefined butterflies". 

From these tours de force (and some others), we learn that the hedylids have a number of surprisingly butterfly-like characteristics, including a second median plate of forewing base lying partly under the base of vein "1A+2A" (quite unlike the configuration in moths) or ventral larval proleg "crochet" hooks not forming a complete circle, unlike the configuration in hesperiids and papilionoids. Or is that last thing an error, since the nerd was supposed to tell us the *similarities* with the non-redefined butterflies, not the differences? 

It seems the coordination between 19th century scientists wasn´t always the best, since the genus name Hedyle has also been graciously bestowed upon a group of sea slugs and one genus of polychaete worms (whatever that is exactly - well, they certainly aren´t butterflies, at any rate, not even redefined ones). It seems the taxonomy of the plants hedylid caterpillars feed on with reckless abandon is even more complex than that of these moths themselves - whoever heard of eurosid II orders or the APG II system?

A more fun fact is that one of the entomologists who researched these insecta was also a talented pianist, and that his name really was Louis Beethoven Prout (no relation to the famous composer, though!). 

I was a bit surprised that the original thesis arguing that Hedylidae are butterflies rather than moths was published already in 1986 in the Bulletin of the British Museum (surely not *the* most obscure source?), since I never seen the hedylids mentioned in any butterfly-associated context ever, so how do we know we´re not dealing with some kind of original research here, which surely must break Wiki´s guidelines? Can the Wiki commentariat please weigh in on this? 

Or no?
