Research - Butterfly Wing movement

I wanted to do a research of the butterfly's wing movement. Since I have never animated butterfly before I was interested to see their movement in show motion.

Butterfly wings are different to bird wings, Butterfly wings are fragile, almost like a tissue paper. Their movement is very fragile as well.

To animate their movement smoothly I will need to practise a lot of their movements as I want their movement to be as smooth as possible in my final film.

A quick practise of their movement from 45° angle.
