I went on the web to see what I could find and there is not a lot on the butterfly. The current excitement is about insects with more rapid wing rotation than is characteristic of butterflies.
------------------------- There are loads of web references on the physics of insect flight, though I couldn?t find any specifically about butterfly flight. For references in my search I used +flight +physics +insect Using +butterfly +flight got me nothing.
The apparent hot item in insect flight is robofly, designed to mimic wing movements of a fruit fly.
And other references.

The following may be deeper than what you had in mind and is similar to the first reference.
