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 actress Ellen Terry as Lady Macbeth, depicted in the painting Ellen Terry as Lady Macbeth (1889).
