This seems to refer to damselflies, and I liked the idea of ‘lustre-coloured’ as lustre is a quality of light more than colour.  I tried to capture its refracting gossamer iridescence by using a gradient colour as background. 

… lustre-coloured damsels were coming out of their shrouds …

Always had a soft-spot for dragonflies and their relations, also the names in French and Italian: ‘libellule’ and ‘libellula’.  And in Chinese there is a lovely four-character proverb meaning to just skim the surface of something: qingting dianshui 蜻蜓点水 (dragonfly dots the water).
