Le Papillon de Nuit translates, roughly as “The Night Butterfly” – a charming fold with a lovely detailed abdomen:

Unlike the other La Fosse butterflies, this one works and then re-works layers on the wings, making the finished model smaller but unique in shape.

There is much to like about this butterfly, but I think the segmented abdomen is fascinating. I folded it in yellow, it reminds me of one of those pests you get around vege patches.
