Today, my colleagues and I were eating lunch outside on an 85 degree fall day. We were enjoying the extra long lunch before an expectedly stressful afternoon when we saw a huge yellow butterfly fluttering around the plumbago near our building. What we thought was a humming bird soon joined the drinking party. Kelly went over to take a picture and she yelled over to us that it was actually a HUGE butterfly. I tried to find a picture of it on the Internet and the butterfly that came the closest was the black swallowtail.
Do you know the name of this butterfly?
