Eastern Tiger Swallowtail - Papilio glaucus - male - nectaring at a Tiger Lily. Before Sunday afternoon's outing, I had never observed any butterflies visiting these beautiful and abundant flowers. I was startled to see a Spicebush Swallowtail doing so on a shady gravel road in Greenwich Township. A few hundred yards farther on I found this ETS doing the same thing. The light was better here - woods on only one side of the road and the flowers on the open side - so this is the one I chose to share.
