Baltimore Checkerspot

This series of images shows the life cycle of the Baltimore Checkerspot (Euphydryas phaeton), one of the many brush-footed butterflies (family Nymphalidae) native to the northeastern U.S.  These butterflies have one brood per year. The larvae are sometimes said to feed exclusively on the plant shown in the last frame, White Turtlehead (Chelone glabra), but I have found the larvae feeding on Purple False Foxglove (Agalinis purpurea) and Common Valerian (Valeriana ciliata) as well.
