I went to a butterfly farm and was so fascinated that I immediately purchased this book upon the completion of the tour. I think it is great for beginners because the pictures are STUNNING (what made it even better was that I was able to identify many of the butterflies I saw in the farm).What I did not like is that there was not enough information about the individual species. I'd like to know if any of the species were endangered, the approximate lifespan, some additional FYI information. But, I think it is great for the library.
