A Very Furry Butterfly
This beauty let me very close while it rested on a stone - this is an uncropped photo taken with my old Nikon D70s and AF 28-105mm f/3,5-4,5D IF @ 105mm and macro-setting.
They're extremely furry and the small scales on the wings are clearly visible here. See the close-up below. Amazing animals - they must have powerful muscles to flap with those big wings.
