Sorry I didn't want to give away my presentation so I held off on making my blog post. But here is the link to the paper I read. It's really interesting to look specifically into the differences they found within the UV patterns and the diets of the caterpillars; I just discussed it very briefly in my presentation. It also talks about some of the photographic techniques used to take these pictures which is also sort of intriguing.
Also here's a kind of strange video that talks a little bit more about the UV butterfly patterns and has some really nice pictures of them.
