Thanks for the nice comments.
Compare this poor little male lizard to the above one - it has clearly recently lost it's tail leaving a pointed stub. Of course they can deliberately do this to help them escape predators but I don't think they ever grow back fully, though please correct me if I am wrong.
The butterfly is a Peacock also at Samphire Hoe last Saturday. Alas it wouldn't pose for me fully open before flitting off, but it's good to see them around.
