I took this shot on 2nd July up the bridle track where four or five nettle plants were covered in mass hatchings of Peacock caterpillars. Don't worry your eyes haven't gone. I've left it blurred to give the impression of a writhing body although in actual fact the movement away from the core was quite stately but they had all dispersed by the next day. These will no doubt be the second flourish of the butterfly on the wing this year which commences late August lasting through September.
