Rainbow peacock spiders may inspire new optical technologies.

• An international study has discovered how male peacock spiders showcase a rainbow signal to attract female counterparts.
• The spiders have abdominal scales with nanoscale diffraction grating structures, which split light into component colours at angles smaller than current manmade technologies.
• The findings could help reduce optical device size and improve spectral resolution, researchers said.
