This may be a silver-spotted skipper. The spot is on the underside of the wings.
Eastern tiger swallowtail.
Unknown skipper. Note the very ragged edge of its wings.
"I celebrate myself, and sing myself,/And what I assume you shall assume,/For every atom belonging to me as good belongs to you.//I loafe and invite my soul,/I lean and loafe at my ease observing a spear of summer grass."
