The Scarce Yellow Sally’s invisibility and ecological fragility successfully sparked discussions with different communities about isolation, well-being, and loneliness. The Art Film 'When Sally Met Sally' straddles the line between scientific reports explaining the significance and importance of the stonefly and the story of Sally, a fictitious character, who recalls, as a 22-year-old woman, the discovery of the Scarce Yellow Sally in Bangor-on-Dee in 1959. Young Sally loves nature, she is carefree and happy, and (just like the Scarce Yellow Sally) loves dancing. 
Today’s Sally compares the fragility and invisibility of the Scarce Yellow Sally to the challenges she now faces in old age and finds that being immersed in nature strengthens her physical and mental well-being.
