Aphid /snail /berry !!!

This is a first for me...
I picked up a sprig of berries that had fallen into the courtyard, on one of the berries was a little silver snail, and walking on the snail was a teeny, tiny aphid!!

Brian says he has never seen this snail in his life before .....

Sorry about the poor quality again, but I had to blow it up quite a bit as it was all so tiny!
