Common Wood Nymph I've been looking for wood nymphs but all I've seen this year have been wood satyrs—well, butterflies. The wood nymphs are typically mid-to-late July fliers, and on yet another hot afternoon, I spotted the first Cercyonis pegala of the season. I love the eyespots in this otherwise nondescript butterfly, and if they do their job of startling potential predators, the nymphs will survive to meet and mate. Then, the females will be ready to lay their eggs on Purple Top and other later-season grasses that should start emerging in August.
