Saw a very dark curled up leaf on a Rosebay Willowherb Epilobium angustifolium that was down the bank on the edge of the Moat. I put on my 70-3oomm lens, to see what it was and found out it was a caterpillar of Deilephila elepenor
This is a hand-held shot at full extension, with me lying down at the top of the bank. It was too steep for me to get closer.
Sorry it's not that sharp.
