I'm trying to make a simple butterfly-material.
I started by searchiung the internet for some good, hi-res butterfly photos - but didn't really find any very good ones. I ended up using this one:

not very hi resolution, and it does not really show the texture or reveal anything about the real quality of a butterfly wing.
I tried to use some imagination and photoshop to "invent" a little more texture and details to the butterfly.

I made an extremely simple model, just a curved rectangle and applyed the material. My model does not look like a butterfly at all, so thiss is all about the material!
Here are some test renderings:
