Seen in Hobbiton

Firstly, I apologise for the lack of comments lately. This tour I'm on is jam-packed with activity and I'm just not finding the time and scarcely the time to upload images. Today I'm uploading yesterday's and today's. So, what's this then? Just something I noticed whilst on a tour of Hobbiton, the film set where The Hobbits were, erm, filmed. Now I've never seen any of these films nor have I read the books, so seeing all the Hobbit houses and the lob called The Green Dragon actually meant nothing to me - but this flower and butterfly did. Anŷone know the name of this flower and this butterfly?
