This butterfly is found only on the Indonesian island of Sulawesi. The arresting colouration is due not to pigmentation but to the effect of refraction – light bouncing off the intricate microscopic structures in the scales themselves. Scientists have attempted to replicate the metallic and iridescent colouring as it could be used in anti-forgery technology for banknotes and credit cards.

The butterfly has been prepared in the UK to museum standards and is displayed in a deep handmade shadowbox frame, mounted on white conservation-grade foam. The back of the frame is covered in really special Italian decorative paper, with a brass hook for hanging it on the wall (but it also stands perfectly on a mantlepiece or a table). It is completely sealed inside the frame and will last for generations.
