Fairygirl - don't knock the white butterflies! There are three common whites: Large, Small and Green-veined, and they are just as interesting as the Tortoiseshell, etc.
Auntie Betty, I doubt that you've seen a Large Blue in Yorkshire - there are only a few colonies on downland in the south of England. If you're in Yorkshire you should be able to find Green Hairstreaks in May/June - a local enthusiast ought to be able to help next year.
Paul, I believe the reintroduced Large Blues were from a Swedish race that was more or less identical to the extinct British one. Not quite sure what you mean by advocating 'More action ... and less surveys'. The records are littered with amateur introductions of all sorts of fauna and flora. For instance, a few years ago it was a scandal that well-meaning enthusiasts were releasing captive-reared Barn Owls into habitats that were unable to support them, and they mostly ended up dead. As for less surveys, how do we find out what we've got? I'd be interested to see some references for the Isle of Wight Large Tortoiseshells. Agree with your call for better habitats for insects.
