Butterflies photographed with an iPhone camera during this morning's walk in the woods and identified to the best of the author's knowledge
The easiest to identify was this tiger swallowtail (Papilio glaucus).
This one with tattered wings was probably an eastern black swallowtail (Papilio polyxenes).
The last one appears to be a great spangled fritillary (Speyeria cybele). I had never photographed this species before; I wish I had had a better camera with me. Glassberg (Butterflies through binoculars, 1999) gives the habitat of great spangled fritillary as "open fields and meadows, roadsides, etc." This individual was alongside a creek in the woods.
