Stop!

'STOP - stop - it's my knee!' he said grabbing it and nearly falling off the grass stalk.! Oh what a wuss! Just look at her expression - it says it all.

However this male ringlet butterfly was having problems. He let go totally, was hanging dare I say by a thread and in the end they had to swap positions.  If you look at my Extra his legs are just not the ticket. He looks exhausted. He clearly does have a louse on his neck so maybe that is the problem. I've tipped this Extra image on it's side to get a better view.
