Hummingbirds are gone and butterflies are fading fast in Maine.
I did have one day about a week ago when the one remaining flowering plant in my wife's herb garden was doing a brisk business with butterflies. I have a National Audubon field guide to New England that I use to identify birds, bees, butterflies, etc. I took the attached photo but can't seem to find it in the guide.
Any ideas to its identity?
Thanks, Chuck
