Starry Night Cracker (Hamadryas laodamia) is a deeply beautiful dark blue butterfly which lives in Central and South America. It makes a cracking sound with its wings, hence its name. 

I just can't take my eyes off of the painting. It looks like Isis with her stars, and the shape reminds me of the Nubian wig worn by Egyptian queens. 

Below is a shot of the painting in the context of my studio.
