The link below takes you to a YouTube presentation about the butterflies to be found on Dartmoor. It's a bit rambling at the beginning but worth watching all the way through with some very interesting observations by Barry Henwood on the White Admiral and some of the Blues. Of particular note is the mobile latrine made by White Admiral larva, with detailed info on how the caterpillar moves it along the leaf.
