Eastern Tiger or Black Swallowtail Butterfly? - Papilio glaucus -
Mountain hardwood forest area between Lake Lure and Old Fort, Old Fort County, North Carolina, USA March 19, 2011 Size: a couple of inches
Is this an Eastern Tiger or Black Swallowtail Butterfly? How can you tell the difference. What about the differences between male and female? Plus, they have a habit of not staying still too long! Thank you.
