Location: Rettenmund Prairie SNA, Black Earth
13:10 - 14:20, 0.6 miles. Many of the Black Swallowtails were hilltopping. There were at least 15 white Clouded Sulfurs but they were more skittish that the yellow ones. The breeding Pearl Crescents didn't want to move. There were enough butterflies that some were probably not counted.
