Help needed to identify

I'm not sure about this one - none of the images online seem to be a close match. It looks a little like a "swallowtail", there again it also looks like a "lacewing". At times like this I realise my student life spent studying music and researching hop products hasn't always been a great deal of help!

Many thanks for all your recent comments, asides, favs (and, on Friday, sympathetic good wishes when the UK was hit by a power cut). All very much appreciated.

Two beautiful shots, I was a student of life and my research into hop products as a merchant seaman hasn't helped with this either!!!

Beautifully sharp but no idea of what it is

Think it may be a Painted Lady Peter. Great macro shot

He doesn't seem to have enough legs - did he seem alright?

@robz Rob, that made me smile. I think it's a trick of the perspective.

Beautiful shot, sorry I can't help with the identification. I cheat and take a photo of the chart at the butterfly house with the names of varieties on it, then when I get home I see which of my photos fit the bill.

Well it seems to be some sort of Longwing (heliconius) which aren't uk native but possibly a butterfly farm escapee? I cant see which it is but its similar to a Postman .
