i saw it when i was out walking at the ethan allen tower and actaully what happened is i stood there watching it and it landed right in my outstretched hand.
that is pretty awesome, but the butterfly chose not to hang around long enough to make it a phot session because while it might be ok landing on you to say hello or "i am enjoying your body heat on this chilly morning", it's made uneasy by you fiddling with your camera to get a picture.
so i had to wait until it settled on a sunny patch on the ground to take its picture to come home and identify it.
also, here's a picture of the tower.
and as a bonus, here is a cute little snake i saw that morning.
and here's a pano of the view at the pinnacle outlook.
