For example, see http://www.ansys.com/About+ANSYS/ANSYS+Advantage+Magazine/On+the+Wing This paper compares Monarch and Swallowtail butterflies that are remarkably similar except for the tails of the swallowtail. See, specifically, the last two or three paragraphs in the right-most column on the 2nd page.
