There's also some interesting biophysics research that strongly
suggests that tails on butterflies (and I would guess, by
implication, moths) increase flight efficiency by helping to shed the
large vortices (generated by their larger-than-needed-for-flight
wings) that interfere with the wing upstroke. 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.
