Scrambling for a model for the day, and finding time to actually fold it, I found a lovely butterfly by Yoshihide Momotani:

This is a Swallowtail, and was designed to be folded in bicolour blue, like this.

A radically different base to the butterflies I have folded from LaFosse, I like the colour management of the wings and the suggestion of a body.

Looking for more models – I have over 100 still to go in this challenge – suggestions of things I have not yet folded are appreciated.
