Location: Black Earth Rettenmund Prairie
Dane County

70s and very windy. Followed the largest male Orange Sulphur I have ever seen for 10 minutes. (solid orange with solid black edge when viewed from top. Only saw it flying. Bottom of wings drab orange.) No picts. The size of a Great Spangled Fritillary. Dwarfed(3-4X) the Clouded Sulphurs that would fly up beside it. 2+X the size of the other O.S.s(or largest female I have ever seen) Maybe another day.
