This, too, is a Sachem, although the "sharply angled band of square cream colored spots on the hind wing" are less prominent.
Notice, also, the brighter color on the ventral forewing, and the hint of blue on the dorsal forewing.Photo taken with a Nikon D70, using a Nikon 200mm, f/4 micro, manual focus lens. Back August 21, 2007.
