A lacy dock leaf

I suspect that there is a very well filled caterpillar seeking a new dock leaf where there is plenty of fresh greenery for eating. 
Google tells me that 'woolly bear' caterpillar is likely to be the culprit.

I've been a bit caught up on the sport on TV today ..... I'll miss Wimbledon but not too long to wait for the Olympics which with no spectators will certainly feel strange.
