Beetlewing

Beetlewing, or beetlewing art, is an ancient craft technique using iridescent beetle wings practiced traditionally in Thailand, Myanmar, India, China and Japan. Notable beetlewing garments include Lady Curzon's peacock dress (1903) and a costume dress worn by the actress Ellen Terry as Lady Macbeth, depicted in the painting Ellen Terry as Lady Macbeth (1889). 

Not sure how I feel about this, but it is interesting. Beetle-wing embroidery: a colonialist fantasia and exotic fad in nineteenth-century England and America.
